New installation commissioning
Check each collimator mechanics and electronics. Full check of controll system Slot and infrastructure (support, cabling, cooling
water) Installation and alignment Vacuum connection and bake-out Collimator standard maintenance

Collimator standard maintenance
Check each collimator mechanics and electronics. Cycle from out to in, to anti-collision and back to
out. Check 5th axis for clearance Check water cooling flow Check temperature sensors Check switches, LVDT’s, resolvers, motors and
drivers Map sound profile for each collimator Check rails Check roller screws

Collimator roller screw replacement (2011-12)
March 03rd 2014
Dust and debris in the end cap and the housing
Some dry screws regreased
Up to date 3 rollers screws have been exchanged.-No linear bearing-2 LVDT‘s-1 motor-2 switches

TIM and Robot intervention
March 03rd 2014
Sound inspection of the collimators done with the TIM in S34 (23/24 April 2012).
Visual and acoustic inspections with camera can be useful in the future (TIM automatically, Telemax robot more flexible).
Vacuum disconnection testing with the Telemax robot on-going.
Use of robot for visual inspections/leak tests (He spray).
Profit from the long shutdown to verify the integration and do some hardware tests to confirm the procedures.
O. Aberle – CWC8
Alignment
March 03rd 2014
Survey is working in the whole machine. During smoothing, magnets will be aligned
and collimators checked (and adjusted if needed).
IR 3 and IR 7 are equipped with additional targets for remote verification with the stretched wire.
New collimators (TCTP, TCSP, TCLP, TCT (TCL6) and TCAPD) will be aligned.
The TCP’s removed during the installation of the ventilation doors + the skewed TCP in IR7L to be checked (high radiation levels, how much deviation can be tolerated?).

Work has just started First ring collimators put back into operational
statusTCLA.7L3.B2, TCP.6L3.B1, TCSG.5L3.B1
A lot of work in parallel with surface preparation and installation activities.
J. Finelle from the vacuum team will take pictures when ever a collimator will be disconnected from the vacuum system.
All collimators will be checked for alignment errors, re-alignement has already started in several points.
O. Aberle – CWC12
Outlook
March 03rd 2014
Improve the sound and image quality for the TIM, very powerful tool for the future.
Investigate on the capabilities of the Telemax or similar robots for inspections and interventions.
Reference sound recording of all collimators? Improve the accessibility to the screw (cap)
(Phase 2!) A regular check during long breaks and shut-
downs with re-lubrication of the screw. Check every slot for 5th axis motion
limitations. Sven De Man is the new reference person for
the LHC tunnel situation concerning collimators
