Controls Requirements for Sector Test - RJL

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

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

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!

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

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

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!

BIC Developments and Testing • Procurements and minor developments in hardware and software remain for the sector test • No problems for cable or fibre procurement as long as no ‘late’ BIC clients • Installation and testing in stages • CNGS extraction tests • TI8 extraction tests • LHC sector test • Phases for each stage: • Installation and stand alone tests • Tests with the user systems • Test link to LBDS • All testing will be done without beam.
