Access & LACS/LASS

The LHC access system has been progressively put in operation starting from Spring 2008 and has been used in different configurations during the LHC commissioning phases (powering tests, beam operation and shut-down). Based on the experience gained during these phases, several modifications have been requested for improving personal safety as well as operational efficiency for the next run. The performances and issues of the LACS/LASS found during the first year of operation will be presented. The status of the implementation for a more efficient operation in 2009 will then be reviewed. In preparation of the re-powering of part of the machine combined in parallel with accesses, possible interlocking of the access system with other equipments (i.e power converter, PIC…) will be finally discussed.
