Beam Commissioning
Based on the TI8 experience, the measures neeeded to reach the
required state of
readiness of TI 2 and TI 8 to deliver beam to the LHC during the
commissioning
phase are discussed. The main objectives for the performance of the
transfer lines
and injections at this stage of the LHC commissioning are outlined,
and the impact
of the lower demanded intensities on equipment and...

Beam Commissioning
oral
The objectives of this phase are enumerated. The key prerequisites
for establishing circulating beam and the procedures involved are
detailed. Given circulating beam,the essential checks, measurements
and associated procedures are clearly established. The time required
for, and the scheduling of, subsystem commissioning is discussed.
The importance of injection scheduling,...

Beam Commissioning
The procedure for ramping the LHC is clearly defined with particular
attention to
power converters, RF and controls. The necessary pre-testing of all
systems is
detailed. Snapback will pose a challenge and the strategy for
dealing with it during
initial beam commissioning is revisited. Measurements and system
commissioning to be
performed during the ramp commissioning phase are...

Beam Commissioning
The procedure for squeezing the LHC is defined with attention to the
squeeze
duration, the variation in magnet currents and the resulting
limitations. The
potential variation in key beam parameters is quantified. The
demands on essential
sub-systems [feedback, instrumentation and controls] are made clear.
The requisite
movement of the collimators and TCDQ during the squeeze are detailed.

Beam Commissioning
It is clear that proper functioning of the beam instrumentation is vital to effective commissioning. How the key
instrumentation is to be commissioned is described including a description of measurements and tests to be
perform with beam during the various commissioning phases. The demands on other systems [controls] are
clearly stipulated. The procedures to be followed to ensure proper...
