LIU-PS review for BE/BI (24-Jun-2015)

General
o Budget codes to be defined for each remaining deliverable instead of a single (64030)
ACTION: Rhodri

Wire-scanners
o SPS prototype installed with electronics to be tested before end 2015
o First planning in place for this large project
o Needs to be presented to LIU management for global check. ACTION: BI
o PS would like prototype installed before LS2 - preferably in H-plane
o ACTIONS:
 BI to decide IF prototype of new design to be built
 LIU to decide where to install if available before LS2
o Specification:
o Beam parameter specifications exist
https://edms.cern.ch/document/1215595/0.1 (JJ Gras et al) or?
o OP emittance specifications need to be added ACTION: OP (Rende) – deadline?
o Uncertainty on final budget
o Review of manufacturing costs with MME in June
o Hope to converge on single design for all machines
o Final cost not known before tendering mid 2016

40MHz Wire-scanner Acquisition
o Awaiting RF input for 40MHz then needs SW adaptation. ACTION: BI & RF

BGI
o


Planning
o End of year 2015 tank installed
o Installation of instrument should also be in YETS 2015
 Need to check that this is feasible for end 2015
 Vacuum compatibility
 Impedance
 ACTION: BI to provide realistic planning
 Simone: detailed planning was presented here
https://indico.cern.ch/event/393678/ in May and the planning was considered
realistic with the final requirement of installing by the end of the 2015-2016
YETS.
o The impedance evaluation was done and presented by the impedance experts
here: https://indico.cern.ch/event/403089/contribution/5/material/slides/1.pdf
during the last impedance meeting study.
o Magnets can come later
 No impact on vacuum
o PS ask for total of 3 systems
 1H, 1V & 1 spare
 Need to check budget covers all of this
 Does not need to include magnet & power converter (separate budget)
 ACTION: BI
o Simone: initial budget allocated was covering 60000 kCHF only for the
prototype, as correctly stated in the EVM comment, instead the total budget
allocated so far was based on the request of 2 installed devices.
BLM Ring
o Still need to find 250kCHF for cabling
o This is the most urgent to allow installation in EYETS if possible
o Requires de-cabling campaign in PS
o Baseline is still to commission after LS2
o May be possible to advance if cabling available
BLM Diamonds
o 16 devices + amplifiers delivered
o Need to clarify 2 spares. ACTION: BI
o Cables need to be installed in YETS 2015-2016
o Is it EN/EL plan? ACTION: BI
o Cables for amplifier chain needs to be included. Impact on budget to be clarified.
 ACTION: BI to update DIC & obtain new cost
o Number of OASIS channels & type of card to be checked. ACTION: Stephane Bart Pedersen
 Simone: Production of BLM supports should be started well in advance the installation of the
slow BLMs because the same support is proposed to be used also for the fast BLMs. Magnet
experts should be asked (Simone?) if the slow BLM system has to be removed during the main
magnet refurbishment during LS2. If that is the case, then we should clarify if it would make
sense to advance the installation of the slow system in a YETS just before LS2.

Injection SEM
o Grid wire spacing needs to be equivalent to ring spacing.
o Should be the same as consolidated ring grids
o ACTION: BI to confirm that grids will be replaced & provide wire spacing

Turn by Turn for Ring SEM
o Old systems (mechanics) to be replaced (CONS)
o Budget (200kCHF) too large for only electronics.
o Proposal to move 100kCHF to cover BLM cabling
o ACTION: LIU to confirm (OK’ed by Simone and LIU-PS)

Wall Current Monitor
o 2 devices ready - awaiting plan with vacuum for installation YETS 2015-2016
o ACTION: BI to clarify plan with VSC
o Decision on acquisition system pending attenuation/protection system design. ACTION: BI

High Bandwidth BPM
o To be installed YETS 2015-2016.
o Are cables installed? ACTION: BI
o Simone: BI should check also the acquisition of the HB BPM. An OASIS channel similar to the
other existing HB BPM would be perfect.

TT2 BPM complete
o Budget used was OP-LIU
o Recuperate 16kCHF for BLM cabling
