Description
The Beam Interlock System (BIS) forms the backbone of the LHC Machine
Protection System, allowing 100’s of distributed User Systems to
inhibit beam operation and request Beam Dump from all around the LHC.
he requirement for rapid response time of the BIS is coupled with
very high safety constraints, as whilst providing a secure and robust
protection. The system should not be a source of unnecessary beam
dumps.
After a brief reminder of the architecture and the technological
choices, this presentation shows the sequence of the steps which
leads to the commissioning of the Beam Interlock System. At the end
of this phase, the system is fully tested from any connected User
System to the LHC Beam Dumping System interface. The presentation
describes how the commissioning is firstly performed in stand-alone
mode through extensive checks from any User System connection to the
Beam Permit generation. The second part of the commissioning involves
each connected User Systems in order to guarantee their own beam dump
request capability.
