  3. Guidelines • The sector test will take place in November 2006 and will be the first injection of beam into the LHC • This will be last chance for full scale tests before commissioning starts in 2007 under very tight time pressure • The successful operation of the Control System is an important goal of these tests • As much as reasonable of the Control System will be tested • Tests will aim for the final solution, special developments will be avoided • Chairman requested cover of Beam Interlocks • In general take Hardware Commissioning as given Controls Requirements for Sector Test - RJL

  4. Summary • Installation of Controls Infrastructure • Timing Aspects • Beam Interlocks • Controls Software Services • High Level Applications • Conclusions Controls Requirements for Sector Test - RJL

  7. BDI – BLM, BPM, BTV, BCTF • Tunnel far front ends controlled through WFIP. Crates will send data back to surface front ends through optical fibres • The surface front ends are a major VME system currently being procured • Sector test will be the first large deployment of FESA! Controls Requirements for Sector Test - RJL

  8. General CO Commitment for BDI VME acquisition systems: Configuration of fan-trays for all VME64x systems Configuration needed to (re)boot systems Provide CPU, timing receiver modules and necessary cables Hardware and software configuration being discussed Special CTRV module for energy transmission over P2 bus (SLP) SR8: 3 BLM systems in rack BY02 4 BPM systems in racks BY03 and BY05 Ethernet and LHC timing event reception OK LHC telegram handling working yet ??? BIC cables pulled – to do SR7: 3 BLM systems in rack BY02 4 BPM systems in racks BY03 and BY05 Timing missing, dead-line April 2006 BIC cables pulled – to do UJ76 (BTV) to do Ethernet and slow timing missing, dead-line September 2006 RR77 (temporary BCT): Ethernet, slow timing + pre-pulses missing.

  9. LHC Layout Assets Controls configuration Data from operation BT, BDI Installation Summary • In general • procurement and installation are in hand • Purchasing limits need monitoring • Cables, services also OK if no late clients • Hardware and software configuration data still to be captured but first discussions have taken place. • No beam time needed to check controls infrastructure Layout – slots, functional positions Assets – physical equipment and it’s attributes Configuration – logical view, addressing equipment, generating software Controls Requirements for Sector Test - RJL

LHC MTG Energy/Ring Intensity/Ring Safe Beam Flag CPS and SPS telegrams and timings and MTG synchronization when filling LHC MTG Safe Params Main MTG GMT LHC Preloaded Injector Sequences Preloaded LHC Sequence 3 BST Cards BST Clocks: Bunch Clock 40..8 MHz. Frev ticks at 89us. 40.00 MHz GPS clock 1PPS (1Hz) clock Basic period clock 2.2 G-Bit / S optical link 64Mb Reflective memories External Conditions and Events Controls Requirements for Sector Test - RJL

  12. The MTG During injection the LHC events will carry synchronisation information and timing pulses to the LHC RF in point 4 to drive pre-pulse generation and it is expected that a few other events will be needed for the injection kicker system and data acquisition equipment. High Priority for CO sector test goals Upon an LSA ramp command the injection dialogue will end and the MTG will free run. Events will be required e.g. Start Trim and Post Mortem Considerable timing development and testing remains. Significant interruption of the CERN timing may be necessary for test and deployment Controls Requirements for Sector Test - RJL

  13. Phase 1, 43 bunch is a complex transfer LSA Sequencer requests beam Ring, Bucket, Beam, Batches The request can only be made after injection of previous batch into LHC Batch 1 in Booster before request is made! Challenge for CBCM May extend filling cycle in early years Master ship transfer and destination changes need to be specified Sector test simpler but must be used to check all this out Transfer and Sequencing LSA Beam Request RF re-phasing SPS PS PSB Controls Requirements for Sector Test - RJL
