> 08:00 While the rates appeared to have quietened around 7am they are back to their previous rate now. > > They still seem to be working on the setting. Implant rate in AIDA about 8 per spill. Thick degrader is still in place > They have collected 25 minutes of implantation data. They are analysing this data to confirm the PID > > 08:38 The PID confirmation was apparently run number 4. During this run they were implanting Cd in AIDA DSSD2 > > 09:09 They are now taking data implanting somewhere in the snout. I have turned off no storage. > Unfortunately we are writing to NOTAPE R3. I was unable to change it as they were already taking data > Data rate 16.3MB/s > ucesb shows similar rates in SC42 and AIDA01. We may be implanting Te in AIDA then. > > 09:35 They stopped the DAQ as their is no beam. Switched the tapeserver over to R1 in directory S496. Setting to no storage > > 09:47 Beam back turned off no storage. On file R1_10 > > 11:04 Now that we have implants on the detector we get a better look at the strips > From the 1d pattern it is obvious that there is an adapter card misaligned in DSSD1- attachments 1 and 2 > This adaptor board corresponds to FEE11 > > 12:17 Leakage currents screenshot 512.png > > 13:30 Beam off. Expected back at 15:00... > > 14:09 Making use of the beam off time NH and HA entered S4 to investigate FEE1 and FEE11. > They noticed FEE11 was off and have realigned that. All channels are now observed in that FEE > They couldn't see anything wrong with the connector for FEE1. We are still missing a block of channels there. > Rates are as before. No better, no worse. > > 15:31 Leakage currents screenshot 513.png. They are continuing to rise following the intervention in S4. It could just be because the temperature is rising...
