- 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
- 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 |
