  1. Data eXchange Coordination • Ongoing Meetings with project engineers and experiments • Compilation of summary report (EDMS 772011) • Coordination of cabling • Coordination of deployment of H/W Now under approval LEADE/ D. Swoboda

  2. WP documentation EDMS 772011 v.3 LEADE/ D. Swoboda

  3. Thilo PAULY on 2006-10-02, 15:44 said: Accept Generally OK, but I have two major comments. Pages 4 - 5 - 7 - 10 - 5 Typo in caption for Table 2. 7 I'm confused about the number of fibres for TTC+BST, and it seems that the spares are not treated consistently in this document.3.3: TTC = 5 signals + 1 spare4.1: 6 TTC + 2 BST + 1 spare4.2: Table 8: TTC 5 + 2 spares 10 First two bullets under status: Isn't the full VME crate requested by all experiments, in order to receive the safe beam TTL levels? To my knowledge ATLAS so far differs from other experiments that they have additionally requested (and received) a PCI-card (CTRP) for the GPS time-stamp. Jorg WENNINGER on 2006-09-30, 11:03 said: Accept Ok - except that I'm not in charge of supplying the mode (or even impleneting it). That is more a general LHC Control System issue. Daniela MACINA on 2006-10-02, 10:05 said: Accept The functional specifications about the experimental interlocks (EDMS 653932) say that the movable devices can move from their garage position when beam is STABLE or UNSTABLE. In addition, during UNSTABLE beam the near detectors are supposed to move as fast as they can to their garage position. It is not clear to me that the GMT system provides to the experiments the SAFE information about UNSTABLE beam (it provides it only on STABLE beam). This issue should be clarified as soon as possible since it is fundamental for the operation of the movable detectors. Pages 4 - 5 - 4 I am not anymore the link person for TOTEM. The new linkperson is Walter Snoeys. 5 Line 4: harwired injection inhibit is also present on the position of the movable devices since the interlock on the position fully exploits the functions of the BIC. Comments to 772011 LEADE/ D. Swoboda

  4. EXPERIMENT BEAM INTERLOCKS • Beam abort and injection inhibit signals can be generated by each detector and each experimental magnet. • Beam abort requests are transmitted over hardwired links to the beam interlock system. • A hardwired injection inhibit is presently only foreseen for the ALICE ZDC acting on beam 1. • All other injection inhibit requests use the DIP system links. Table 3: interlock signals from Experiments LEADE/ D. Swoboda

  5. TTC instrumentation analog version: 2 Rx/TX per VME module, digital version: 3 Rx/TX per VME module LEADE/ D. Swoboda

  6. BPTX beam collision timing Item Type Supplier From To Date • Resolution @ 450 GeV/c ? BRAN beam collision rate LEADE/ D. Swoboda

  7. BIS beam interlock system • BIC cabling provided to patch panel in rack specified by experiment (FoC). • CIBU installed by AB-CO in rack specified by experiment (FoC). • Cabling CIBU  patch panel tb provided by experiment. Connector and grounding specified by AB-CO. • Cabling BICpatch-panel has been requested (DIC). TS-EL defined cabling campaign. • CIBU available 1Q07. Installation and commissioning tbd between AB-CO and experiment DSS. • Patch-panel space required 1U/channel. • Question:is UPS required for CIBU? • Are PPs needed? • Totem CIBU location? LEADE/ D. Swoboda

  8. BIS cabling in Experiments LEADE/ D. Swoboda

  9. Defined domains are: ACC – Accelerator Domain TS – Technical Services Domain ALICE – ALICE Experiment Domain ATLAS – ATLAS Experiment Domain CMS – CMS Experiment Domain LHCB – LHCb Experiment Domain technical services domain: VENT – ventilation COOL – cooling ELEC – electrical distribution ACC – access control GAS – primary gas SAFETY – CERN Safety Systems experiment domains: DSS – Detector Safety System GCS – Gas Control System MCS – Magnet Control System DIP naming scheme * 1st level of possible sub-domains could be as follows • accelerator domain: • PS – PS machine complex • SPS – SPS machine • LHC – LHC machine • CRYO – cryogenics • VAC – vacuum *LHC Data Interchange Working Group (LDIWG) Phase 2 – Final Report LEADE/ D. Swoboda

  10. Naming of Data published by experiments via the DIP * * Naming scheme proposal for LHC  experiment data in work by C. Kostro LEADE/ D. Swoboda

  11. Machine to experiments • https://twiki.cern.ch/twiki/bin/view/Leade/WebHome LEADE/ D. Swoboda

  12. status of data exchange systems LEADE/ D. Swoboda

  13. cable end point in experiments [1] TTC Fibres for CMS go directly via the Machine Tunnel from Point 4 to Point 5, they do not pass the CCC/R as for the others [2] BST Fibres are two per ring LEADE/ D. Swoboda

  14. data exchange H/W in experiments [1] Cabling type VH4 launched at all XP sites.Termination through 1U pp with 12 Lemo or Canon 9p. [3] Original arrangement between B. Puccio (AB/CO) and E. Sbrissa (PH/DT1) was that E. Sbrissa would install the correct cable between the BIC and his CIBU. E. Sbrissa is ok with someone doing it for him, however, and will supply the final rack location ASAP. LEADE/ D. Swoboda

  15. cost of data exchange systems for experiments [1] Computed prices including the price of the transmitters from SR4 to experiments LEADE/ D. Swoboda

  16. cabling planning in experiments [1] Cable type CMC50 replaced by CMA50. LEADE/ D. Swoboda

  17. LHC exchange Action Items • Each Experiment to determine what is missing • Agree with suppliers to get commitment on scope and time • Organize missing issues LEADE/ D. Swoboda

Circulating beam type/ring RF parameters Next injection parameters Safe Beam Parameters Beam energy/ring Beam present flag/ring Safe Beam flag/ring Safe collimator flag Post mortem 40 MHz PLL clock Beam intensity/ring LHC machine mode Fill number Particle type/ring GMT features GMT parameters also included in BST frame: GMT exclusive parameters: • Official request by Atlas. Other experiments need to submit request. • CTRV modules will be installed on request only. • Experiments need to specify precise requirements, i.e. triggers , post mortem, etc. • Fanout from CRTV << 100 m. • Cost (CRTV + crate) ~ 20 kCHF. • AB-CO will provide cabling to rack specified by experiment.
