Description
Machine protection consisting of passive and active systems will be used to prevent
damage during the LHC injection process. Concerning beam 2, parts of the SPS
extraction and transfer line beam interlock system has already been successfully
tested during the TI 8 commissioning. Key elements of the final system for beam 2
will be validated during the LHC sector test with low intensity beam, together with
parts of the passive protection system, the TDI and at least one transfer line
collimator TCDI. The remaining issues after the sector test will be discussed in
detail, where the entire injection protection system together with post mortem,
management of critical settings, sequencer and software interlocking system must be
tested with beam, for different intensities and filling patterns during the LHC
beam commissioning. Requirements from other systems and interdependencies for test
modes, such as inject & dump, are important input for the overall LHC commissioning
strategy and will be discussed.
