Previous Day
| | Status: entire IVC and 100mK can removed. All mixture in dump. MB vacuum jacket has been pumped out. |
| 0835 | Remove Cf source from on top of G101c in clean room and return source to safe |
| 1045 | Remove G101c from purge. Take photos of bonded channel splits on Side 2 and Side 1 |
| Side 1 |
 |  |  |  |
| | Near DIB1 (d2) | Near DIB4 (d1) |
| Side 2 |
 |  |  |  |
| | Near DIB1 (d2) | Near DIB4 (d1) |
| 1055 | Put G101c in bag to move to bonding room |
| 1115 | Remove G101c from bag in bonding room. Exposed to unclean environment for 30 minutes. |
| 1130 | Repair wirebond on DIB1 Side 1 pA. Initial resistance checks look OK. Took a few tries to bond to tungsten pad on detector, had to increase power
Wirebonder settings: Bond 1/2 Power = 480/485, Bond Times = 40/30, loop height = 50 mils, drop before clamp = 26 mils |
| 1220 | Remove PTF tape and dental floss holding thermometer around spool. Take off spool to reveal mixing chamber screws. Tighten mixing chamber screws, which do seem to have gotten slightly looser. |
| 1234 | Add IR LED chips to source holder with plate in top position. There should still be room to fit the tower thermometer in the center. |
| 1239 | Clean spool and reattach spool to bottom of mixing chamber. |
| 1330 | Remove G101c from bag in bonding room. Exposed to unclean environment for 60 minutes. |
| 1420 | Rewire DIB4 Side 2. |
| 1435 | Rewire DIB4 Side 1. |
New DIB4 wirebonding scheme:
| DIB4 Side 2 | pA not connected, pB-TES8, TES8-TES7, TES7-TES6 |
| DIB4 Side 1 | pC-TES1, pD-TES0 |
Now it is wired in such a way that we can use the HV board without using rerouting boards.

| 1455 | Return G101c to clean room |
notice DIB1 side 1 pin 2 bond broken again, crud.
Resistance checks:
| Detector | G101C | DIB | 4 | |

| 1530 | Put G101c back in purge |
| 1700 | Remove spool because we put it on too soon. |
| 1745 | Place Cf source inside purge cabinet for overnight activation of G101c. |
| 1750 | Finish tightening screws on upper (copper) IVC can. |
