lWe can sub-divide
the various LHC systems into the following categories:
l Triggered
systems (via specific external event) :
č• beam
instrumentation
č• power converter
system
č• RF system
č• …
l Self-triggered
systems :
č• quench
protection system
č• beam dump
system
č• power converter
system (on faults ?)
č• …
l Non-triggered
systems :
č• Interlock
system, BIC & PIC
