  2. VI. Controls for the movable BIDs • Devices concerned • Scrapers (beam shaping and diagnostic) • MEBT dump and Beam stoppers (safety relevant) • Work status • Define the limit of scope of the workpackage • Define the actuating systems and FE electronics • Create the Xml files for BIS controls • Define the controls and cabling schemes • Define the size and location of the patch panels R. Folch EN/STI - BID Workpackage Review - March 2012

  3. Scraper horizontal Master LayoutMA-00492-a-THA-V1.1 Scraper vertical Beam Stopper (4x) MEBT Dump

  4. Control scheme for the scrapers 2 x Scraper Vertical (MR-0011-SCV-A) 2 x Scraper Horizontal (MR-008-SCH-A) BD? Intermediate control rack Main control rack WP limit BID BD Conection box Electrical actuator (Brushless motor) DC supply & Encoder < 10 m 10-30 m R. Folch EN/STI - BID Workpackage Review - March 2012

  5. Risk of radiation on scrapers drivers? • CERN uses stepping motors with radiation hard resolvers, and has no data on the radiation sensitivity of the opto-encoders of the brushless motors • CNAO uses brushless motors and does not consider radiation effects as a critical issue (no failure expected < 10Gy) • MedAustron simulations for the ionizing dose rate < 0.1 Gy/y (scrapers losses not considered) • MedAustron decision: • OK for brushless motors for scrapers • Design for easy replacing of the driving in case of failure R. Folch EN/STI - BID Workpackage Review - March 2012

  6. Beam interlock interface design • Applicable to safety related devices • Beam stoppers (BST) • MEBT dump (BDM) • Reference document R. Folch EN/STI - BID Workpackage Review - March 2012

  7. Definitions, channels, specifications ES-100107-a-MMA v.1.3 R. Folch EN/STI - BID Workpackage Review - March 2012

  8. Beam Interlock System signals for the beam stoppers and the MEBT dump BST BDM R. Folch EN/STI - MACS Week - October 201108.2011

  9. XML files for the Interlock Control The XML files for the 4 beam stoppers and the MEBT dump are completed and uploaded on SVN according to WP CO procedure

  10. Control scheme for the BST and the BDM 1 x MEBT Dump (ME-00-000-BDM-A) 4 x Beam Stoppers (Tn-00-000-BST-A)n = 1, 2, 3, 4 WP limit BID CO Beam Interlock System rack Beam Intercepting Device BID patch panel v K (free) (free) - OUTR (wired to CR for redundancy) OUTR (wired to CR for redundancy) - OUT(BID is out of beam) OUT (BID is in the beam) - IN (out of beam) PLC - Veto (in beam, ignore -IN) Pressure sensor (to CR?) Cable NEA 18 Pressure regulator Pneumatic cylinder Compressed air supply Pressure sensor Electro-valve 1-3 m 10-30 m R. Folch E/STI - BID Workpackage Review - March 2012

  11. Cables routing and patch panel Proposal from D. Grenier based on Linac 4 design R. Folch EN/STI - BID Workpackage Review - March 2012
