I'm sharing this list as a guide to which alarms I clear on activation, as opposed to those I respond to according to the guidance provided. Operators who are more or less familiar than I am with the status quo of operations on site should communicate with each other and system leads for updated procedures

• 4K_TCS:
  • H1:TCS-ITMX_LSR_HDTEMPDEG: This alarm corresponds to the temperature of the TCS laser head for H1's ITMX. Although the temperature of the laser head was stable (typically +/- 0.01 DegC), it was in a HIGH alarmed state, so Cheryl instructed me to shut down the laser. By Monday, this issue should be resolved.
  • H1:TCS-ITMY_LSR_HDTEMPDEG: This alarm is the same as above. The laser was off but the temperature was below the allowed range, so the range may need to be adjusted.
• FMCS:
  • H0:FMC-CS_LVEA_ZONE4_E_DEGF: This alarm corresponds with the temperature sensor labeled 4-E, in the Northwest part of the East Bay. The thermometer is giving a flat 0 DegF, which converts to a flat -17.7 DegC. RichardM is aware of this problem.
• Temps
  • H0:PEM-LVEA_DST8_TEMP: This alarm corresponds to the temperature readout from Dust Monitor 8 in the South Bay of the LVEA (according to the H0PEM_DUST MEDM). It alarms because there is no signal. Patrick is aware of this.
• H0DUST
  • Assorted alarms with white alarm states: The white alarms indicate no signal to various dust monitors. Patrick is aware of these.
• Vacuum
  • Ion Pump alarms in LVEA northwest of GV3 and GV4, corresponding to vented H2 volumes.
• 4k-PSL
  • H1:PSL-FSS_RCTEMP: This alarm corresponds with the temperature of the Reference Cavity of the H1 PSL, which is also very sensitive to temperature fluctuations. If the temperature, as compared to earlier days, looks cyclical and virtually the same as the previous period, I contact MichaelR to update the alarm values to reflect seasonal changes.

All other alarms are responded to according to the guidance provided by the EPICS Alarm Handler. Stay tuned for door alarms in a different post.
