VI. Controls for the movable BIDs
15.03.12
• Devices concerned– Scrapers (beam shaping and diagnostic)– MEBT dump and Beam stoppers (safety relevant)
• Work statusDefine the limit of scope of the workpackageDefine the actuating systems and FE electronicsCreate the Xml files for BIS controlsDefine the controls and cabling schemes • Define the size and location of the patch panels

Risk of radiation on scrapers drivers?
15.03.12 R. Folch EN/STI - BID Workpackage Review - March 2012
• 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

Beam interlock interface design
• Applicable to safety related devices– Beam stoppers (BST)– MEBT dump (BDM)
