R. Folch EN/STI - BID Workpackage Review - March 2012 2

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)
