Matching of the west arm

After the work on the north arm (#55889 and #55886) this morning we made the matching for the west arm with the TCS off (DAS and RH).

We did the following steps:

  • 1336903483 10:04:25 UTC scan of the arms with the green lasers CARM_SET_scan(3)
  • 1336904178 10:16:00 UTC L1z 20000 Backward
  • 1336904358 10:19:00 UTC CW 10000 Backward
  • 1336905198 10:33:00 UTC scan of the arms with the green lasers CARM_SET_scan(3)
  • 1336905918 10:45:00 UTC L1z 20000 Backward
  • 1336906158 10:49:00 UTC CW 20000 Backward
  • 1336905198 10:58:00 UTC scan of the arms with the green lasers CARM_SET_scan(3)
  • 1336907418 11:10:00 UTC L1z 20000 Backward
  • 1336907658 11:14:00 UTC CW 20000 Backward
  • 1336905198 11:22:00 UTC scan of the arms with the green lasers CARM_SET_scan(3)
  • 1336909103 11:38:05 UTC scan CARM_SET_ONmode(0,2)
  • 1336909222 11:40:04 UTC scan CARM_SET_scan_12(2)
  • 1336909809 11:49:51 UTC L1z 20000 Forward
  • 1336910645 12:03:47 UTC scan CARM_SET_scan(1)

In conclusion, we moved the L1z by 40000 steps backward. Analysis will follow.
