Hardware Commissioning & Cold Checkout
Collaborative effort between several teams and groups. RWA, LHC MAC 12/07
LTC Extended meeting
Tuesday 04 March 2008 11
Deliverables• Outcome of the collimator hardware commissioning:
– Validation of single collimator, all relevant functionality– Settings and sensor readouts (position, temperature, switches,...) verified– Control of each collimator from CCC is declared “safe”– Machine protection functionality (without beam) partially established
• Cold checkout focused on:– Control an ensemble of collimators– Address timing and synchronization issues– Function-driven motion, “tracking” tests with other equipment– Establish full machine protection functionality without beam– Verify interfaces to other accelerator systems
• Beam loss monitors: configuration/acquisition of distributed system• Sequencer driven commands, machine modes• Verify logging of distributed systems (big data sets!)
– Consistency and sanity checks; global system status

Validation of single collimator, all relevant functionality
Tuesday 04 March 2008 13LTC Extended meeting
Validation of single collimator, acceptance up to installation
Tuesday 04 March 2008 14LTC Extended meeting
Validation of single collimator, manufacturing and operational data
The hardware commissioning of the collimators include all the tests that will be performed once the collimator is installed in the tunnel in order to validate their correct functioning. These include tests on infrastructure up to the base support, tests of the tunnel equipment, on the full system and with the collimator under vacuum.
Systems:TCL, TCLIA, TCLIB, TCLIM, TCT, TCTVB, TCLP, TCHSH, TCHSS, TCHSV, TCLA, TCAPx, TCP, TCSGRequirements:Commissioning 1 (C1, access needed): Collimator installed, cabling finished. Tests with cross check in tunnel (two teams).Commissioning 2 (C2, no access required): C1 + bake out terminated, under vacuum, water flow nominal. Remote tests (one team)Infrastructure:Power, light, Water cooling, Vacuum, Cabling, Collimator installed, Ethernet, GSM.

• No piquet service foreseen
• Expert telephone list
• Depending on problem:
1. Disable collimator
2. Minor intervention (remotely, expert tool)
3. Intervention in tunnel (Failure: Stepping motors, Read-out (switches, LVDT), roller screw;limited intervention, preventive maintenance and monitoring;Impact: Few hours up to 2 days)
4. Collimator exchange (Failure: Important vacuum or water leak, mechanical damage;exchange collimator; Impact: Several weeks downtime, RP, transport, vacuum and bake out involved)

Summary
LTC Extended meeting
• Final installation in Week 17
• Transfer lines commissioned, to be finalized
• Point 5R commissioned (C1) with final procedure, special setup in Point 6 this week.
• Commissioning of sectors one by one is still feasible, but very tight
• Performance of phase 1 collimation system will by only assessed after the completion of the installation during the shut down 2008/09
• Piquet/Experts:-No Piquet service foreseen, first years of LHC operation will tell more-Experts phone list
