Description
The LHC beam vacuum system operates at cryogenic and at room temperature. Many
aspects such as the location, the level of the leak flux, the reparability, the
impact on the machine commissioning and operation shall be taken into account when
dealing with vacuum leaks. The detection of warm air leaks is a difficult but mostly
well mastered technology. Special attention will be paid to He leaks in a cryogenic
environment which could arise during the period of beam commissioning and beam
operation. The qualification of these leaks against beam operation, the diagnostics
means and tools, the repair schemes and the expected downtime are discussed.
