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

Worked with Haitham on Sector 5
Moved Kraken to SL2
Began confirming signals on S5 sense wires S5 Testing and Performance Summary
Add missing oscilloscope image SL2-STB6-K1200872 U10
Confirmed with Haitham that HV burin is completed for SL2 R1S5_SL2_BurnIn
Rotated Sector 3 with David
11/16/2013
Confirmed signals on S5 SL2 sense wires. Found eight wires not listed in S5 Testing and Performance Summary without signal. Will test again to verify.
Super Layer STP Board Wires without any Signal Notes
SL2 STB1-K1200874 1,4,19
SL2 STB2-K1200875 0
SL2 STB3-K1200873 0
SL2 STB4-K1200869 83
SL2 STB5-K1200871 - Was unable to get signal on board for any wire. This board is currenty being debugged. All boots out.
SL2 STB6-K1200870 1
SL2 STB7-K1200872 7,19,67,72,82 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.
Super Layer STP Board Wires without any Signal Notes
SL2 STB1-K1200874 1,19 Noise, but no signal. U19 has large noise as seen previously on STB7-U67. Putting in missing boot did not change anything.
SL2 STB4-K1200869 -
SL2 STB7-K1200872 7
