Wednesday July 7

Past 24 hours

• Malte and Mark worked on FCAL modules replacement [1]
• One of the RF crates had been disconnected, Beni fixed it [2]
• Bobby and others worked in the tagger hall during the day

• production data taking continued on Pb
• established operating field of solenoid. First regular production run on Pb ?
• DAQ issues early afternoon. Sergey worked hard to fix. Started initially with rocFDC11 busy causing DAQ to hang. after necessary reboot of roctrig1 the trig_client process on gluon100 stopped communicating with roctrig1 so no trigger rate data went to EPICS anymore. see logbook

Shift reports

• day shift summary
• swing shift summary
• [ owl shift summary]
• [ early riser shift summary]

Issues

• Sean found that the TOF RF signal is mssing since run 100477: see logbook Our check procedures are clearly not vigilant enough anymore. RF signals are NOT in online monitoring anymore and Hydra is not doing its job as intended.
• switching back from AMO to Diamond the cross hair on the camera does not match the position with the Diamond. However beam seems to be in the right spot as there is a coeherent peak in the tagger microscope with the expected rates as well as the DAQ rates make sese. see lobook

Plans

• maintenance day: beam will go away 7:30am, 8 hours maintenance, followed by beam restoration and high current beam tuning for HallC
  • please access hall after 9am: other halls have priority
  • ramp solenoid to 800A for cyro comprssor swtch
  • FCAL base replacement
  • Tagger NMR inspection
  • Fix TOF RF signal
