7. III) BLM naming conventions (from A. Nordt) BLMCC  Mobile monitors (not for analysis) BLMDI  Dump line ionization chambers (useful for analysis if not saturated i.e. not at 23.168 Gy/sec, installed in the dump line) BLMDS  Dump line secondary emission monitors (not useful for analysis) BLMEI --> Ionization chambers (all locations except at quadrupoles) (important for analysis) BLMEL  Little ionization chamber (at the moment for testing reasons, not for analysis) BLMES  Secondary emission monitors (not useful for analysis) 7 12/6/10

8. BLM naming conventions (from A. Nordt) BLMQI  IC installed around quadrupoles (important for analysis) BLMI  Names with "BLMI.number:EXTRACTIONLOSSES_EXTR1" describe the BLMs in the injection lines, extraction for one SPS cycle in Gy/sec, there is no running sum, 1extraction==20ms (can be used for analysis) BLMPI  there are no data logged (not for analysis) BLMPS  4 monitors in the LHC dump line, data not logged (not for analysis) BLM2I  Ionization Chambers (installed in various places), different in gain and phase compared to BLMEI, BLMQI, but see the same losses as BLMEI or BLMQI monitors (important for analysis) BLMXD  32 Diamond detectors around CMS. They use the same electronics as we use for the LHC BLMs and they have 12 RS and 12 Thresholds for each RS. They are calibrated and the losses can be compared with the losses from LHC ionization chambers (can be used for analysis) 8 12/6/10
