Common Chapters shared by BI proceduresList and description of tests per architecture layersTests sorting per commissioning phases9Procedure State 4/4We agreed with the HWC team and the MTF providers that we will extend these procedures, originally limited to initial HW commissioning, toMachine check-outs, repeated each shutdownsCommissioning with beamRegular tests during the run (good as new)

The procedures are currently reviewed to include these new tests.10Nominal Workflow = Outline of my TalkMonitor InstallationHWC Procedure DocumentationManufacturing & Test Folder Instantiation NC HandlingGetting Access during others HWC periodsHWC of our monitorsUpdate MTFReady for BeamMachine Check-Out11BI Manufacturing and Test Folders 1/3We use the MTF steps to log our tests result forHW commissioningMachine check-outsBeam commissioning and regular test results will be kept in the operational logging DB

We also use the MTF properties to store information on layout or performance measurement performed during installation for the distributed systems BLM & BPM. These properties will be used for the initial online configuration of the monitor software and the control layout maintenance.

13MTF 3/3: BPM Properties

14NC Handling 1/5Most of the time, problems detected during installation or HWC (broken electronics, bad connectors) are treated and fixed immediatelyIn some rare cases, this is not possible (i.e. non conformity on a BPM in a cryostat). In these cases, we issue a NC document via the monitor MTF in the corresponding step.15NC Handling 2/5: BPM NC

Free AccessNo AccessRestricted AccessRF Tests No Access for Months!22Access Conditions 3/5We have to pass after inter connections (BLM/BPM in the arcs) and after bake-out in the LSS.cope with co-activity and access conditionsco-habit with RF in point 4 where most of our individual systems are concentrated (no collimators or inj/ext kickers)So our time is counted and we work in close collaboration with planning and HWC teams to organize our interventions23Access Conditions 4/5We evaluated and listed all the interventions we still have to do for the HWC of our instrument.We maintain and update this list in a file shared with planning and HWC teamsWe classify intervention per sectors with the following color schema

24Access Conditions 4/5This gives:

25Access Conditions 5/5Every week, we eliminate what has been done and Valentina (Planning Team) tells us what we can do next weekadds contingencies (interconnect re-opening, second bake out of a zone)warns us if access conditions change during the weekThis not easy but necessaryWe hope that this will become an habit for everybody in the coming weeks to avoid recent hiccups (agreed access refused once in the tunnel)

Well have to find some agreement with RF to get some access during their tests26Nominal Workflow = Outline of my TalkMonitor InstallationHWC Procedure DocumentationManufacturing & Test Folder Instantiation NC HandlingGetting Access during others HWC periodsHWC of our monitorsUpdate MTFReady for BeamMachine Check-Out27Beam Position MonitorsAll electronics cards (tunnel & surface) are first passed through a test bench where parameters of relevance for nonlinearity correction are stored in MTF.The full cabling & BPM chain (small coax, cryo feedthough, cryo-cables, button feedthrough) is tested during HWC for non conformities. Some 14 NC (out of all interconnects) have so far been created, of which we have managed to bring approx half back into tolerance by changing the components - the others are still marked as NCs. The origin of these NCs are all slightly different (cryocables not firmly connected, overtightening of cryo-flange connections, damaged cryo cables), but half of them were found in sector 6-7, and all had passed a similar test in SMI2.BPM mapping checks are systematically performed after installation (i.e. ~80% of LHC system is already verified for this).Finally, Sputnik tests allow full commissioning of FIFO acquisition mode, which will be used for beam threading

If these tests are successful, the system will be ok for machine check out and the only things left to do with beam should then be the polarity checks the fast timing set up of all BPMs.28Beam Loss Mon.All electronics cards (tunnel & surface) are first passed through a test bench where parameters of relevance are stored in MTF.The full cabling & BLM chain is tested during HWC.The HV modulation and acquisition via test signals together should check every channel response and correct mapping.The test via RA source seems nevertheless necessary for this critical system. This second check of functioning and configuration of the system will reduce the errors. We have at many locations a mounting and dismounting of monitors, which potentially increases the risk of making mistakes that would make the diagnostic and tuning with beam of the system even more difficult.

If these tests are successful, the BLM system should be ready for machine check-out and beam commissioning 29Beam TV Monitors- 31 cameras (out of 33) are installed and aligned - 31 associated electronics are installed The 31 systems have passed the hardware commissioning tests (steps defined for MTF) 'locally' and throught the VME systems (BTV cards with VME acces CTRL).Everything is up to date in MTF. The 2 remaining systems are waiting for machine installation progress (point 8: back-out to be redone week 13 and point 2: back-out week 14(?))

BTV systems should be ready for machine check-out and profile measurements30Wire ScannersMechanics and detector installation in the tunnel are done on right side and in progress on left side, including local test.US45 electronics installation will follow before the end of March allowing full acquisition chain checks.

If these tests are successful, the BWS system will be ready for machine check-out and profile measurements in the bunch averaging mode. Bunch by bunch profile acquisition will require fast timing tuning.31Synchrotron Light TelescopesBSRT RA43 (beam 2) In place, currently in HWC, to be followed by Cold check week 14 BSRT RA47 (beam 1) In place , HWC starts with access in week 12, cold check week 19 Then the Video acquisition will be ready, calibrated to the test target, all data transmissions checked as far as CCC, and left running with a test target during the following cool down.The fast cameras will also be fitted (even before the intensifiers are available) to enable run time load and data transmission tests in the HWC and machine checkout phases. The intensifiers will be fitted during a short access to be defined in May/June (TDB with RF).

After machine check out, the BSRTs will be ready for initial beam commissioning (apart from "just before beam" access). "just before beam" is a 1 hour access needed to set the hardware from target to machine light. 32Ionization Gas MonitorsHWC of the warm magnet have been done. They are ready for machine check out once their operational mode will be agreed.The camera, optics and tunnel electronics plus the US45 electronics will be installed by the end of the month allowing acquisition and control chain checks.Well most probably need a local pressure bump to see 2008 low intensity beams. The original design to inject gas agreed with AT/VAC is now considered risky by AT/VAC who would like to investigate other options. The current agreement is that they will install what has been foreseen but that injection will only be used on dedicated MD and not on standard routines

BGIs will be ready for machine check out beginning of April but most commissioning with beam issues will be linked to the available gas injection system.33Beam Current TransformersTunel and alcove electronic will be ready for HWC on week 18. Several diagnostic and simulation units are foreseen to test the calibration procedures

These systems will be available for machine checkout from 4-5 cool-down onwards (~ week 21) Both should then be ready for beam expect high band width acquisition mode of the fast BCTs (bunch by bunch acquisition, dump line) which will require fast timing tuning.

34Luminosity MonitorsBRANB Pt 2&8 ; BI MonitorsThe electronics installations will be finished for the end of March. We will then remove detectors and re-installed as late as possible since they are not necessary during the HWC and machine check out phases and would not survive an un-announced bake-out.

If these tests are successful, these monitors will be ready for machine check out in April and the following tuning will be left for beam fast timing and coincidence synchronisation threshold scans background evaluationBRANA Pt 1&5 ; Berkeley Monitors2/4 chambers installed: one has a dead quadrant and both need modifications (do not stand the nominal High Voltage)Two more chambers are expected some time in April, No electronics installed as none exists yet. Our feeling is that it will at best be "just in time".BI envisage to install temporary scintillators/PMT systems as plan B in case something goes wrong with the ICs.

If we manage to install and HWC these monitors in time , commissioning with beam will be as for BRANA

35A word on global TestsEMCLocal effect of Kickers in Pt 6 (extraction), 2 and 8 (injection), 4 (tune and aperture)RF in Pt 4Collimation motorization in point 3 and 7On our instrumentation (Pick-Ups, BLM, BTV and BCTs) will be tested in collaboration with the concerned AB groups.

UPS infrastructureBI has INB critical systems (BPM, BLM and BCTs) under UPS to ensure that Post-Mortem buffers are retrieved and stored even during a major power cut. Should we check that nothing has been forgotten along the whole acquisition line?36Nominal Workflow = Outline of my TalkMonitor InstallationHWC Procedure DocumentationManufacturing & Test Folder Instantiation NC HandlingGetting Access during others HWC periodsHWC of our monitorsUpdate MTFReady for BeamMachine Check-Out37Machine Check OutOnce HWC is ok, we can start machine check out of an instrument in order to Check its integration in the control systemCheck its functionalityDebug it as much as we can before beamHave people involved (commissioners from OP/ABP) knowing and 'owning' the systems.

38Machine Check OutWe will base this activity on the summary dashboard on our Wiki Web.

Test of the software public interface agreed with OP/ABPRBAC implementation will start when the configuration tools will be ready 2 dedicated test servers are in place to assess our logging needs before migration to operational serversFixed Displays and Graphical User InterfacesTesting processes introduced in the LHC sequencer to regularly (ie before each fill) check the status of our instruments 39Machine Check OutThe BI SW responsible of the instrument will organize the continuous assessment of its instruments, ie:find/organize time slots, also outside official dry runs, where conditions allowing to test a (or several) box of the dashboard are met.Invite the instrument team members to test the box together or by sub-groups depending of the casemaintain the dashboard info up to date (color scheme and details on the box dedicated page) and prepare battle field for the next iterationWell also prepare a sequence of events (injection, BLM/BPM/BSRT/BQ measurements, start of ramp, beam dumped,...) and ask Mike to play it for us regularly outside dedicated dry runs. Like this, we should be able to progress between the ooficial dry runs.

40Machine Check OutIn addition to this, we will also participate to the LSA dry runs. This dashboard should help the organiser to know what they can use

The details of this approach will be discussed next week during LHCCWG and we hope to be able to launch this activity during the second half of March on several individual systems

Finally, AB/BI do not see the need today to have a piquet service during the HWC and machine check-out period and will organize these tests during normal working hours.41Nominal Workflow = Outline of my TalkMonitor InstallationHWC Procedure DocumentationManufacturing & Test Folder Instantiation NC HandlingGetting Access during others HWC periodsHWC of our monitorsUpdate MTFReady for BeamMachine Check-Out42ConclusionsBI HW commissioning for individual systems starts really now that we can. Most of it will be finished before RF tests start again but we will need some accesses in point 4 during this period.Distributed system HWC is in progress following installation

Machine check out will follow HWC instrument per instrument and will be done in collaboration with the OP/ABP commissioners
