  1. Ferrites in BE-BI Preliminary Data Compiled by R.Veness with information from W.Andreazza, B.Dehning, D.Gerard, R.Jones, L.Soby

  2. Introduction • Definition • In this context, a ‘ferrite’ is any material used for suppressing HOMs (i.e., could also be SiC or other) • Completeness • It was not possible to collect a complete picture of ferrite use in BI, as: • The time available was limited • Documentation for some systems is not complete or available

  3. Ferrites in Wire Scanners • PS FWS • 5 new tanks installed in 2011/12 • ‘FERROXCUBE’ PLT 100/100/6/H-4SD60 as per EDH 2542526 • UHV cleanedat CERN, thenheat-treatedat 400 C • 2 blocks installed per tank • SPS BWS • No recent modifications made to ferrites • ‘FERROXCUBE’ 4S60 (same as above?) • Treatment and quantity TBC

  4. Ferrites in Wire Scanners • PSB and LHC • Information lessclear for the moment • Either 4S60 or Philips ferrites (fromF.Caspers) • Baked-out, but temperature TBC • Quantity TBC

  5. Wall Current Monitors • PS WCMs • Installed in SS03 and SS95 • Material T240/160/20-8C11 • 5 rings in each WCM • Treatment TBC • Also contain RF-absorber tiles • CTF3 WCMs • 5 pieces in 10 GHz WCMs

  6. Other • PS CODD pick-ups • Each pick-up contains 2 tiles of RF-absorber ferrites
