09:40 → 10:00 The BLM system of the LHC injector complex

Description of the Beam Loss Monitor (BLM) system of the LHC injector complex, with emphasis on the new electronics for the measurement of currents with a dynamic range covering 10 orders of magnitude.

Speaker: William Viganò (CERN)

10:00 → 10:20 Real-Time FPGA-Based Algorithms for the BLM system of the LHC injector complex

Description of real-time FPGA-based algorithms for the combination of Beam Loss acquisition methods, used for the expansion of the dynamic range of current measurements.

Speaker: Eva Calvo Giraldo (CERN)

10:20 → 10:40 Q&A session

10:40 → 10:55 CLAWS for Beam Abort in SuperKEKB

Recently we established that we can reliably observe beam aborts in the CLAWS system. With a read-out update we can issue a beam abort signal a couple of microseconds earlier than the Abort Diamonds.

Speaker: Ivan Popov (MPI Munich)

10:55 → 11:25 Discussion

Organisation of the next step: update of the specifications for the beam loss (radiation) monitors and beam abort systems in the interaction region, aiming at a first draft for the June 2020 B2GM.
