Suspended Platforms
• Order placed with ALCLIC (CH)
• Two suspended platforms will be delivered (with CE-certificate) end of
February 2006.
• Acceptance by SC hopefully early March 2006
• Work on their integration
(guiding and suspension) in
the muon system currently
ongoing.
• To speed up installation of
services (cables, gas pipes,
etc.), ordering of a 3rd
platform is foreseen.

Chamber Support Walls
• Production for M4+M5 panels finished,
for M2+M3 ongoing in COSPAL (IT)
• Panels have precision holes for ‘balconies’
• A prototype wall has been extensively
tested in LNF with a load of 1.8tons
• Installation in LHCb from March-May 2006

Services: Cabling
Concept:
Horizontal routing
for cables between
and behind chambers
Confection and testing of cables for
stations M4+M5 ongoing at CERN,
using prototype cables.
-> The rest to be done in Italy.

Services: Gas System
Overall design:
• Described in EDMS document 463077.
• Distribution racks for M2-M5 with 18 ch. manifolds have been installed.
Internal Gas Piping:
• After the ageing test we decided
to connect chambers in parallel
-> Impedance adjustment will be done
using capillaries ( 0.5mm,
2.5cm long)

Services: Cooling
Cooling for FE-boards:
• In order to avoid hot spots close to the beam pipe in M2/M3, air
blowers are foreseen for both sides, providing an airflow of about
400m3/h (enough to remove about 2.5kW of dissipated power by air).
• Distribution principle:
Temperature reduction
due to cooling:
ΔT2,3 ~ 7.5oC
Hoses have 30mm diameter
• Something similar is planned for M1
• Schedule: Blowers for M2-M3 ready for installation in April 2006

Chamber Positioning
• The chambers will be correctly
positioned on the walls (~1mm
precision), using the precise positioning
of chamber supports (‘balconies’) as
starting point.
• The position of each chamber will be
measured with respect to reference
points placed on the border of the half
station support panels by means of a
laser distance meter.

Muon System Installation schedule
• Chamber support panels and services will be installed by technicians
of the collaborating institutes
-> 104 man weeks
• Chambers and electronics will be installed and commissioned
by 2 teams of 3-4 people of the muon group -> 220 man weeks

Conclusions
•
Despite the delay caused by the installation/commissioning
of the cryoline, good progress has been made with the
muon system infrastructure in 2005.
•
The schedule for the installation of the M2-M5
infrastructure, services and chambers remains tight and
requires close monitoring.
•
We are aiming at having M2-M5 completed and as much as
possible of M1 installed at the LHC start-up in 2007.

M1 Integration
Status:
•
Work on M1 integration has been resumed in 11/2004
(M2-M5 integration had and has priority)
Issues which have to addressed:
•
•
•
•
•
•
Gantry design and impact on M1
-> done
Constraints from neighbouring detectors -> established
Attachment of M1 on the top
and guiding on the bottom
-> ideas exist
Racks for M1 in the ‘bunker’
-> ok
Cable routing
-> extensive studies required
Cooling issues
-> study has to be resumed
Plans:
•
Solve outstanding issues in 2005.
•February
Implement
infrastructure
for M1B. Schmidt
in 2006
