System changes 2010/2011

• Operational, procedural and SW changes• HW changes and activities • Electronics and control changes

Operational, procedure and SW changes

• Update LBDS for 4 TeV (tracking tables, voltage clamps)– If 4 TeV table and voltage updated with relatives tests associated. Etienne– If 4 TeV later in the year then time foreseen for test.

• New IQC functionality (LHCb BCM, TL trajectories, synchro error...)– System test Conditions MTG injection, SPS cycling Verena/Lene

• New IQC latching philosophy– Ongoing Lene/Delphine

• Implement operational settings for MKIs– Setting for MKI Brennan/Etienne– During setting up

• Tighten energy interlocks for TCDIs/TDIs/TCLIs– Setting up with Beam Brennan

• New XPOC data modules and BLM ratios– New module to compare TCDQ – Beam position BPMS – System Test Jan/Nicolas Magnin

Operational, procedure and SW changes

• BLM changes (to collate with BLM team)– System Test Brennan/ BLM team

• Shielding installed for TCDIs and TDIs– TCDIs done– TDIs not for start up

• New injection procedure and ppm requests for intermediate beam– Verena

• Additional interlocking of injection oscillations– Verena/ Lene

• TCDI automatic setting up– 2 priority not critical Brennan

HW changes and activities

• MKD • Generator consolidation (to run up to 4 TeV), as we do during each small

tech. stop - exchange of 3 MKD generators– Done and tested (Jan/Senaj)

• Normal maintenance without any impact on LHC operation (equipment inspection, measurement of magnet contact resistance, change of one or two terminating resistors on MKI, etc.)

– Ongoing (Jan/Senaj)

• New TI2 BPMs and dual-plane acquisition for all– Check logging

HW changes and activities

• MKI• MKI2 replacement (magnet B at point 2)

– Done Mike Barnes– Conditioning delayed due to vacuum activities (coils for electron cloud)– Conditioning expected to be finished 24/1– Careful PFN investigation on MKI2 – Commissioning start 17/2 – Access needed in UA23

• MKI 8– No change – Vacuum coils installation ongoing– Conditioning start 1/2

Electronics and controls activities• ALL systems

– Software upgrade Etienne• Ongoing >> When finished test from sequencer and application program (Arm, Inj Dump,

Circulate & Dump)• BIS ok Timing ok

– General maintenance Etienne• Ongoing

• LBDS– New dump triggering IPOC– New TSU IPOC

• Ongoing test after with conditions. Not critical for start up– TSU firmware upgrade (audit follow-up)

• Done test needed Etienne– Additional MKD internal current diagnostic

• Ongoing – Update BEM firmware to correct any bus communication errors between

BETS and PLC• Done ok

– New thermal working point for MKD generator cooling system. Validation required.

• Ongoing system test after.

Electronics and controls activities• MKI

– SbS extension (PFN secondary voltages + MAIN switch currents)• Ongoing system test after.

– Increase sensitivity of fast interlock• Will be done system test after.

– Implement additional diagnostic for KISS monitoring / failure diagnostic• Done Update By (G.H. &Lene )

– Fine synchronisation improvements (reject noise captured from CIBO)• Ongoing system test after. (Tentative improvement not sure will completely be

solved.)– Resynchronisation of AGK

• Needed machine check out condition ( timing synchro, prepulse BIS ok and all remote control 5 hrs.)

– Deployment of new KiTS software version with additional diagnostics for timing• Done update by G.H

Recommissioning• Specific tests of all modifications

– Will be done as far as possible in system tests– Integration tests involving ABT systems:

• Timing system upgrade: GPS down: no injections; injection sequencer, injection cleaning + soft interlocking strategy, ...

• Some need fully-connected systems (BIC loops, access, DCCTs, timing, pre-pulse, RF): estimate 2-3 days of connected checkout needed

Machine check out • Sequencer

– DATABASE– 1. New simplified database scheme that allows– 1.1. simplification of the sequence components definition ==> easy to maintain since the number

of components is greatly reduced;– 1.2. new functionality:– 1.2.1. inheriting mechanism;– 1.2.2. possibility to restrict the execution of sequence components to a given set of beam modes;– 1.2.3. who, why, when the sequence was modified;– 2. The sequences/tasks will be only accessible in the development database by the

ROLE lhcSeqEditor and tested using the development server of the sequencer. Once they work, they will be copied to the PRO database for normal execution. Therefore the PRO database won't be accessible directly anymore. A roll back mechanism will be supported to allow to roll back to the previous version in case of problems.

– 3. All the operational sequences will be moved to the new schema, the unused tasks/sequences will be deleted.

– The new database schema is already in the development DB and has been provided by CO/DM who is developing an API to easy the access to the data (no more direct queries). The API will be ready by end of January and then the Sequence Editor and the Sequencer Core will start implementation. This development will be done in the development servers and will be deployed as PRO once tested and validated. Most likely the full database functionality will be implemented in the sequencer core in steps. As first step the core will be updated to use the new schema; as a second step the inheriting mechanism will be implemented.

– SEQUENCE EDITOR With the new database schema, a new editor will be developed, more user friendly and with more functionality.

– NOMINAL SEQUENCE(S) Will be reviewed and re-structured to map the way we operate the machine.

– Components of the type CHECK-SET, where the SET is implemented as “on error task” will be substituted by ENSURE tasks where appropriate.

Recommissioning• Specific tests of all modifications

– Will be done as far as possible in system tests– Integration tests involving ABT systems:

• Timing system upgrade: GPS down: no injections; injection sequencer, injection cleaning + soft interlocking strategy, ...

• Some need fully-connected systems (BIC loops, access, DCCTs, timing, pre-pulse, RF): estimate 2-3 days of connected checkout needed

• System beam tests– Subset of full 2010 checks: synchronisation, basic aperture checks, system

functionality tests, interlocking checks, steering, protection device setup and validation, asynch dumps, ...

– Full tests needed in areas where systems have been modified (MKI, MKD, TSU, ...)

– Specific tests also for 4 TeV (BETS, protection)– Abort/injection gap commissioning and full operational deployment– Needs full breakdown, but expect that this is of the order of 12-14 shifts with

beam – to be confirmed before fixing this number• Follow-up of intensity increase

– Standard tests as beam intensity increases
