UPDATE: THE PROBLEM IS SOLVED FOR NOW:

Doing the calib for the 5th time eventually worked.

------------

The ADC check showed that the calib test for aida5 failed.

We tried to do the calibration as described in the fail message, but it seems to not work. See attachement.

Power, Ethernet and HDMI cables connected to FEEs. To prevent cables coming out of connectors, power and HDMI cables are zip tied to FEE cooling pipe (see attached image).

Correct FEE MAC addresses have been updated in /etc/dhcp/dhcpd.conf

Remote access to carme sever has been setup. Remote access instructions in elogs 176-179. 

New ASIC settings which reflect polarity of FEES produced 2022Jan27-16-43-00 

New Options file updated to point to new ASIC settings. 

/MIDAS/config/TclHttpd/carme-gsi@8015/startup.tcl updated for 8 FEEs 

/MIDAS/Linux/startup/NewMerger Updated line from "./master64 -i 16 -l 16 -p 11001  &" to "./master64 -i 8 -l 16 -p 11001  &"

Quick motors test performed. Motors accesible remotely (elog 179). Motors moving output (BNC 1 on motors box) connected to motors module (BNC 1). When not moving +12V is observed at BNC 2 on motors module. When moving 0V is observed on BNC 2.

No obvious beam or signal of any kind. Temperatures OK.

00:13 DAQ continues OK. System-wide check OK. Temps OK. Still no clear sign of beam.

01:03 Daq continues OK. System wide checks OK, Temps OK.

Only low energies observed in the energy spectrum. Looks a bit like the low energy noise observed in our previous runs with no/very few counts above what would be beam energy (~7.6 MeV)

Note the xy plots are not all orientated correctly (strips are correct in the sort code but root axis need to be flipped - I can;t remember how atm). The part of the plots with counts are those closest to the beam. 

02:00 DAQ continues OK. System wide checks OK. Temps OK.

Spectra still looks the same. I have noticed the right hand side rate is higher than the left. EyEx cut spectrum also looks like much more counts outside of the cut.

03:40

DAQ continues. All checks and temps OK.

I can now see a small peak at 5 MeV in the bottom left dssd. This dssd also has the least number of counts in the low energy continuum.

I have logged back into grafana on x2go to get the number ions in the ring. Attachment 17

04:23 (05:23 EU)

DAQ stopped, merger stopped, tape server stopped. Bias OFF. FEEs turned OFF. Screen shots taken of the monitoring code plots - not yet uploaded.

Windows and servers remain up in case we want to do some more tests in the near future.
