Aberle – CWC March 03 rd 2014
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 4 O. Aberle – CWC March 03 rd 2014
Collimator standard maintenance � Check each collimator mechanics and electronics. � Cycle from out to in, to anti-collision and back to out. � Check 5 th 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 5 O. Aberle – CWC March 03 rd 2014
Collimator roller screw replacement (2011 -12) 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 6 O. Aberle – CWC March 03 rd 2014
TIM and Robot intervention � Sound inspection of the collimators done with the TIM in S 34 (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 ongoing. � 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. 7 O. Aberle – CWC March 03 rd 2014
Alignment � 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 (TCL 6) and TCAPD) will be aligned. � The TCP’s removed during the installation of the ventilation doors + the skewed TCP in IR 7 L to be checked (high radiation levels, how much deviation can be tolerated? ). 8 O.

Schedule – linked to LS 1 LHC planning � Work has just started � First ring collimators put back into operational status TCLA. 7 L 3. B 2, TCP. 6 L 3. B 1, TCSG. 5 L 3. B 1 � 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. 11 O. Aberle – CWC March 03 rd 2014
Outlook � 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 5 th axis motion limitations. � Sven De Man is the new reference person for the LHC tunnel situation concerning collimators 12 O.
