23. Beam loss detection

Bernd Dehning (CERN)

The ILC or CLIC beam loss detection will have to function as a protection and tuning system of the beams. Losses need to be measured at numerous locations and depending on limits action have to be initiated by the system. With the triggering of automatic actions the aspects of reliability and on the other side the consequences of wrongly initiated actions have to be regarded. The talk...

24. Studies for the CLIC TBM BLM System

The CLIC 21 km main linac and corresponding 24 drive beam decelerators are arranged into modular structures referred to as the 'two beam modules'. The baseline technology choice for the CLIC Beam Loss Monitoring system (as presented in the conceptual design report) is based on ionization chambers for the two beam modules. However, a more cost effective BLM design, based on Cherenkov light...

25. Diagnostics for Machine Protection at FERMI@Elettra

Lars Fröhlich (Sincrotrone Trieste)

07/06/2012, 10:00

The talk presents the design and performance of the main diagnostic subsystems of the MPS for the FERMI@Elettra free-electron laser: Beam loss position monitors based on the detection of Cherenkov light in quartz fibers with multi-pixel photon counters, conventional ionization chambers with a novel frontend electronics package, and solid-state RADFET dosimeters providing an online measurement...

26. Equipment fault detection

Mr Bruno Puccio (CERN)

The organization and the setup of the equipment interlocks are described through the CERN Beam Interlock System (BIS) solution. The latter is the common solution to protect various types of CERN accelerators: ring (LHC, SPS...), linear (Linac4) or transfer lines. The BIS is more than a protection system, it is the key element to get efficient beam operation, to enhance machine availability and...

27. Beam Quality Assessment for the LHC beams real time and post-mortem

Verena Kain (CERN)

The LHC has stringent requirements on transverse and longitudinal beam quality to avoid beam instabilities, maximize transmission and performance. Dedicated automatic quality checks are carried out in the last LHC injector and in the LHC after each injection. These systems have successfully indicated problems with beam quality at many occasions and guarantee the required excellent performance...
