  1. Loss of fill 2734 • Global Post Mortem Event • Event Timestamp: 15/06/12 15:54:55.343 • Fill Number: 2733 • Accelerator / beam mode: PROTON PHYSICS / STABLE BEAMS • Energy: 3999960 [MeV] • Intensity B1/B2: 15691 / 15005 [e^10 charges] • Event Category / Classification: PROTECTION_DUMP / • MULTIPLE_SYSTEM_DUMP • First BIC input Triggered: First USR_PERMIT change: Ch11-BLM_MSK: A T -> F on CIB.SR7.S7.B1 R.Schmidt / I.Romera

  2. Loss of fill 2734 [ms] [ms] R.Schmidt / I.Romera

  3. From BIS logs BLM triggered Beam dump request PIC only sees the Powering problem after ~60ms

  4. From PIC R.Schmidt / I.Romera

  5. Loss of fill 2734 – change of orbit B1 R.Schmidt

  6. Loss of fill 2734 – change of orbit B2 R.Schmidt

  7. From FGC • Power converter only sends Powering Failure at 15:54:55.420 • -One can see strange jump in current some ms before…

  8. Beam losses beam 1 for fill 2734 R.Schmidt

  9. Beam losses beam 2 for fill 2734 R.Schmidt

  10. Comments • This has been one of the standard cases during the design of the MP system, and the reason for the diverse redundancy in the systems • We would not have dared to test such case with high intensity beams • MP worked as expected….. • EPC should investigate how to send out a Powering Failure event in such case • In order to no only rely on the BLMs, the Fast Beam Current Change Monitor is required … R.Schmidt / I.Romera
