- Goals
- Confirm signals on all of Sector 5's sense wires
- Finish HV burnin: S:F:G = 1500:-750:536 and the current draw is less than 1 uA CLAS12_R1_S5_QA
- After the above is completed, stop gas flow, Install dust covers, prepare for shipping
- Test TDC integrity using DAQ and S1
- 11/8/2013

Was unable to get signal on board for any wire. This board is currenty being debugged. All boots out.

U67 has a lot of noise.
|
- SL2 has been in HV burnin: S:F:G = 1500:-750:536 and the current draw is 1-2 uA on the sense wires. Has not gone down after a week.
- 11/21/2013
- The 2 Fold HV Power Supply still reading between 1-2 uA. Could be readout on power supply. According to Wiki the burnin for S5 SL2 is complete.
- Retested signals on seven wires not listed in Testing Summary for signal. Could get signal on five of the wires checked.
