INTRODUCTION 1.1 INTRODUCTION TO CERN The European Organization for Nuclear Research (CERN) is an intergovernmental organization with 20 Member States*. It has its seat in Geneva but straddles the Swiss-French border. Its objective is to provide for collaboration among European States in the field of high energy particle physics research and to this end it designs, constructs and runs the necessary particle accelerators and the associated experimental areas. At present more than 5000 physicists from research institutes world-wide use the CERN installations for their experiments. 1.2 INTRODUCTION TO THE LHC PROJECT The Large Hadron Collider (LHC) is the next accelerator being constructed on the CERN site. The LHC machine will mainly accelerate and collide 7 TeV proton beams but also heavier ions up to lead. It will be installed in the existing 27 km circumference tunnel, about 100 m underground, that previously housed the Large Electron Positron Collider (LEP). The LHC design is based on superconducting twin-aperture magnets which operate in a superfluid helium bath at 1.9 K. 1.3 INTRODUCTION TO THE SCREEN MONITOR A screen monitor installed on a beam line permits to visualise at its location the beam transverse dimensions. The spot of light it produces is imaged on a TV camera and provides a direct representation of the beam cross-section. 2. SCOPE OF THIS TECHNICAL SPECIFICATION This Technical Specification describes the characteristics and the requirements of the mechanics of a new screen monitor. This type of monitor is needed at CERN within the framework of the LHC project. These monitors will equip the two LHC rings. 3.

LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 6 of 24 4.2 CONTRACT EXECUTION 4.2.1 RESPONSIBILITY FOR DESIGN, COMPONENTS AND PERFORMANCE CERN reserves the right to make minor modifications to this Technical Specification before placing the Contract. Unless clearly stated by the Bidder in the tender document together with a justification, these minor changes shall not affect the contractual price that shall remain fixed. The Contractor shall be responsible for the correct performance of all items supplied, irrespective of whether they have been chosen by the Contractor or suggested by CERN. CERN’s approval of the design and component choice does not release the Contractor from his responsibilities in this respect. CERN assumes responsibility for the performance of items and sub-systems supplied by CERN. 4.2.2 CONTRACT FOLLOW-UP 4.2.2.1 CONTRACT ENGINEER The Contractor shall assign an engineer to be responsible for the technical execution of the Contract and its follow-up throughout the duration of the Contract. 4.2.2.2 PROGRESS REPORT The Contractor shall supply, within one month of notification of the Contract, a written programme detailing the manufacturing and testing schedules. The programme shall include preliminary dates for inspections and tests. A written progress report shall be sent to CERN every three months until completion of the Contract. 4.2.2.3 DESIGN APPROVAL AND PRODUCTION The detailed design is provided by CERN and must be approved by the Bidder. Component ordering and equipment manufacture shall not start without CERN’s written prior agreement. A prototype of the TV monitor mechanism has been built at CERN to verify that the performance is met with the proposed design. The series production shall be preceded by the production of one prototype unit. Production of the series shall not start before CERN has given its formal approval of the prototype in writing. 4.2.3 DEVIATIONS FROM THIS TECHNICAL SPECIFICATION If, after the Contract is placed, the Contractor discovers that he has misinterpreted this Technical Specification, this will not be accepted as an excuse for deviation from it and the Contractor shall deliver equipment in conformity with this Technical Specification at no extra cost. During execution of the Contract, all deviations from this Technical Specification proposed by the Contractor, the Tender, or any other subsequent contractual agreement, shall be submitted to CERN in writing. CERN reserves the right to reject or accept such proposals without justification. LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 7 of 24 CERN reserves the right to slightly modify this Technical Specification during execution of the Contract. The consequences of such modifications shall be mutually agreed between CERN and the Contractor. 4.3 FACTORY ACCESS With advance notice, it shall be possible for the CERN representatives to have access during normal working hours to the manufacturing or assembly sites, including any subcontractor’s premises, during the Contract period. The place of manufacture, as stated in the Tender, may only be changed after written approval by CERN. 5. TECHNICAL DESCRIPTION OF THE SUPPLY 5.1 GENERAL Proton bunches will be injected at 450 GeV in the two LHC rings via two transfer lines, TI2 and TI8, Fig 1. Five TV screen monitors distributed in each ring of the LHC will be used to visualize locally the transverse section of the injected beam. This technical specification contains the necessary information for the manufacturing of the mechanical part of these monitors. It is based on a detailed mechanical design completed at CERN after study of the required performance and of the constraints related to installation. The injected proton beam population will range from 5.109 protons to 4.9.1013 protons. Therefore two screens shall be alternatively used to cover this intensity range: one 1 mm thick Al2O3(Cr) screen, for the lower part of the range, producing light through luminescence, and a 12 m Titanium foil used at higher intensities providing optical transition radiation (OTR) when it is traversed by the beam. A linear mechanism sets one of the two the screens IN beam or can remove them both to parking positions to release completely the vacuum chamber aperture for the beam. When a screen is set IN, it is tilted by 45 degrees with respect to the beam axis. The light produced by the beam passage is extracted horizontally outside the beam vacuum chamber through a radiation resistant vacuum window. It is then analysed by an optical system composed of filters, lens and camera. When injection studies are completed, the screens are removed to parking position and a dummy chamber attached to the screen mechanism is set in order to ensure the vacuum chamber continuity. Hence, the impedance seen when the beam circulates in the ring is minimized. LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 8 of 24 Figure 1: Representation of the LHC machine with the injection regions in the two rings. 5.2 DIMENSIONS AND TOLERANCES All parameters relevant to the monitor geometry are detailed in the appropriate drawings attached to these specifications. Some of the basic parameters imposed by the working environment are mentioned here: adjacent vacuum chamber inner diameter : 80 mm aperture to be covered by the screens: ± 21.2 mm horizontally, ± 30 mm vertically length of the Ultra High Vacuum (UHV) assembly part taken as the distance between the external face of the 2 flanges located at each extremity: 280 mm. two 110 mm extension chambers located at each monitor end will be manufactured and assembled at CERN, making a total monitor length of 500 mm (drawing LHCBTVSI0001, position 7). height beam axis-floor: 950 mm for 4 monitors and 1100 mm for 7 monitors distance: beam axis-alignment line: 490 mm The supporting structure shall cope with the weight of the whole assembly, approximately 90 kg. The support of the monitor must in addition provide vertical and horizontal positioning. The alignment of the monitor with respect to the beam axis is achieved with two surveyor markers foreseen on the top of the tank. The axis defined by these markers must, once the monitor is installed and aligned, coincide with the axis of the beam pipe within 0.1mm. The UHV tank shall tolerate a vacuum pressure down to 10-12 hectoPa. This is a welded structure of non-magnetic AISI 316L stainless steel sheets which must be preformed, machined and LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 9 of 24 welded according to the design and must meet the required tolerances. The dummy chamber and the 2 chambers adjacent to the tank are made of Copper. The mechanical tolerances to be satisfied are specified in the relevant drawings. 5.3 PERFORMANCE The tolerances are specified in order to meet the designed performance of the monitor which is mentioned for information. Under nominal beam conditions, the Titanium foil will be used. The monitor must then provide 1): the beam size with a rms accuracy of 0.1 mm (10% for a rms beam size of 1 mm). the beam position with a rms accuracy of 0.3 mm with respect to absolute references. 5.4 QUALITY Reference must be made to the detailed drawings for the materials to be used. Special care must be taken concerning the materials composing the UHV assembly of the monitor. At any stage of the machining, welding and assembling of a screen monitor the required tolerances must be met. This must be corroborated by tests of the UHV performance of the monitor assemblies and of the precision of the mechanism. Each monitor must be checked at all stages of its machining, mounting and welding to satisfy the characteristics. The results of the checks must be noted and sent to CERN. 6. SCOPE OF THE SUPPLY 6.1 MATERIALS CERN will provide the AISI 316L stainless steel sheets used to manufacture the UHV tank (LHCBTVSI0015) the copper for the two tank end chambers and for the dummy chamber (LHCBTVSI0021 and LHCBTVSI0049). the assembly of the bellow, the flange and the screen support stem made of 316 L stainless steel (LHCBTVSI0003). the Titanium for the manufacturing of the screen support (LHCBTVSI0048, positions 2, 3, 4, 5). the materials (AISI 316LN stainless steel) for the two flanges to be mounted at the ends of the vacuum tank (drawing LHCBTVSI0015, position 2). the flange (AISI 316LN stainless steel) for the light extraction window (drawing LHCBTVSI0015, position 3) the light extraction window (LHCBTVI_0065) 1) C.

Arrangements for the provision of the radiation and corrosion resistant paint of the supporting structure can be settled between CERN and the Contractor. 6.2 MACHINING FOR ULTRA HIGH VACUUM (UHV) Cutting fluids shall be of an inert type, which does not in any way attack the metal surface. Oil containing silicone or halogens such as chlorine or fluorine shall not be used. All traces of cutting fluids shall be removed by a degreasing operation shortly after machining. Special attention must be paid to the sealing surfaces of the vacuum. These surfaces must be protected from damage at all stages of the manufacturing process. 6.3 CLEANING The bellows expansion joints shall be delivered to CERN cleaned, according to ultrahighvacuum standards, and ready for installation. The cleaning procedure to be used is described in Annex C, (provided by AT/VAC). Any deviation from this procedure shall be transmitted to CERN for approval. Before the delivery of the pre-series, some witness samples (supplied by CERN) shall be cleaned and sent to CERN for validation. CERN may require the cleaning of more samples during the duration of the Contract. UHV good practice is mandatory; hence special care has to be taken not to contaminate the bellows expansion joints during manufacturing, storage, transport and handling It is important to handle the components exposed to UHV with care and cleanliness. Small traces of grease, oil or heavy organic compound can impair the pump-down efficiency and final base pressure. A strict discipline must be observed in this respect. After any machining and before any welding, each part must be cleaned before starting any final assembling. 6.3.1 CLEANING OF STAINLESS STEEL Before beginning the assembly, the stainless steel components exposed to the UHV must be treated according to the following procedure (Annex C): removal of gross contamination and cutting oil using the appropriate solvent LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 11 of 24 immersion in a vapour bath of perchloroethylene at 125 degrees during at least 15 minutes. ultrasonic cleaning in an alkaline detergent (pH=9.7) solution at 65˚C during at least 30 minutes.

To prevent oxidation, the weld shall be shielded by an inert gas (Argon). TIG welding must be used for the assembly welds of all stainless steel. All welds must be regular, continuous and free from porosity. The welds shall be helium leak tight. 6.5 ASSEMBLY, TESTS The two screens equipping each monitor will be prepared and mounted at CERN but the Contractor shall: Machine and assemble the Ultra High Vacuum monitor tank, including the steel flanges. Install, if needed by the Contractor, a set of two survey markers on the UHV monitor tank for test purposes. Manufacture and assemble the screen mechanism foreseen to work under UHV, including the frames to sustain each of the two screens. Manufacture and assemble the mechanism to control the filters of the optical system, located outside the vacuum chamber. Manufacture and assemble the monitor support which is also designed to position precisely the monitor with respect to the beam axis during the installation (LHC BTVSI0035). 6.6 MECHANICAL TESTS The reproducibility of the screen mechanism must be tested once the assembling of a monitor is completed. Tolerances are specified on drawings LHCBTVSI0049 and LHCBTVSI0050: metrology measurements must confirm that the required tolerances are met after machining of the mechanism, (LHC BTVSI0002). once assembled, the angle of the screen sustaining frames, (45 degrees), and the reproducibility of the mechanism must be checked. If the specified mechanical 2) Trade mark of HENKEL & Cie SA, Dept. D3, CH – 4133 PRATTELN (Switzerland) LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 12 of 24 tolerances are met a reproducibility of less than 25 micrometers (rms) on the position shall be reached. The overall required precision for movement under vacuum must be compatible with the necessary accuracy quoted in section 4.3. Each monitor must be given an identification number, (from BTVSI1 to BTVSI11) corresponding to its position in the manufacturing sequence), which shall be electrically engraved on the tank at an agreed location. This identification number must be quoted on all test certificates. 6.7 HELIUM LEAK TESTING Each individual assembly exposed to UHV shall be leak tight by UHV standards when tested with a global overpressure of 1 bar gaseous helium. Leak tightness of each assembly shall be defined, after applying the foregoing conditions for 10 min, as a total leak rate measured on a calibrated He leak detector not exceeding 1 x 10-11 Pa.m3.s-1 A helium leak detector with a detection limit of at least 1 x 10-12 Pa·m3 ·s-1 shall be used for this purpose. Test procedure shall be approved by CERN. The test protocol that the Contractor intends to follow shall be submitted to CERN for approval before the tests are carried out, according to the following standards: ISO/AWI 12724 Testing for leaks using a mass spectrometer leak detector or residual gas analyser. ISO 3530 Mass spectrometer type leak detector calibration. NFA 09-490 Non-destructive testing - Testing for leak tightness - Recommended practices for the specification and testing of gas-tightness. NFA 09-492 Non-destructive testing - Tightness testing - Method under vacuum with tracer gas. The leak-tightness certification of each individual monitor assembly shall be included in its test certificate. 3 6.8 ENVIRONMENTAL CONDITIONS The monitor will be operated in radiation areas. In order to avoid corrosion, the monitor support steel will be painted, with yellow RAL 1021 paint. Black and mat anodised aluminium must be utilised for the optical system bench, including the motor support. 6.9 CONTROL A DC motor will activate the screen mechanism to generate linear displacements and set or remove either of the two screens or the dummy chamber. The quality of machining and assembling will ensure good positioning at each stage. Ends switches confirm the completion of the required displacement. The nominal mechanism speed is approximately 12 mm/s (depending slightly on cable lengths). As information, a mechanism shall withstand a total number of 10000 cycles during its lifetime. Nine end switches must be mounted, four to be incorporated in the assembly of the screen mechanism, the other five being used in the control of the filter positioning on the external optical bench. Movement without vacuum shall be possible. The Contractor will also handle cabling and electric tests for each monitor. LHC Project Document No. LHC-BTVSI-CI-0001rev1.0 Page 13 of 24 In order to ease the cabling work, two cabling diagrams, one for the screen mechanism and another one for the mechanism of the filters and lamps, and necessary pictures taken of the mechanism prototype will be provided by CERN. After completion of the cabling work, tests must be carried-out for each monitor of the good functioning of the mechanisms. A test box will be provided by CERN to perform these checks when the screens and then the filters are moved. 6.10 TRANSPORT CERN will be responsible for the safe and timely delivery of the necessary materials as arranged with the Contractor. CERN is responsible for the packing and the transport to the Contractor premises. CERN shall ensure that the materials will be delivered without damage and any possible deterioration in performance due to transport conditions. The Contractor is responsible for the safe and timely delivery of all monitors to the CERN Prevessin Site. Every monitor must be packed with protection caps for the end flanges and wrapped in two different parts: the UHV tank with the mechanism and the screen sustaining frames assembled, mounted on the assembled support, (LHCBTVSI0002, LHCBTVSI0015, LHCBTVSI0035 and LHCBTVSI0042). the optical bench with the mechanism to control the filters (LHCBTVSI0022). The Contractor is responsible for the packing and, where included, the transport to CERN. He shall ensure that the equipment is delivered to CERN without damage and any possible deterioration in performance due to transport conditions. 7. DELIVERY SCHEDULE Delivery of the eleven monitors shall be organised according to the following steps, starting from the date of selection of the Contractor: Within three months, production of a prototype unit. After evaluation of the prototype and written approval by CERN, a batch of four monitors (five in total) shall be available at CERN within the three months following the approval letter. The necessary actions must be implemented both by the Contractor and by CERN in order to ensure that this stage takes place by the end of 2005, as the assembling, testing and installation of three monitors are needed by the end of February 2006. six extra monitors are required by the end of March 2006.
