| 1110 | Begin tower installation |
| 1145 | Tower adapter plate attached and all screws torqued into 30mK can. Attach thermometer, and check that the connection is made. Lakeshore bridge should have the Tower Thermometer reading ~1kΩ. Currently reading 1.0001kΩ. Looking good. |

| Striplines may be hanging a little lower than in recent runs: |

| IT4 Side Coaxes | ||
|---|---|---|
| Face | Length | ID |
| 1 | Short (position 1) | ST-3-10 |
| 2 | Medium (position 2) | ST-4-9 |
| 3 | Long (position 3) | ST-5-11 |
| 4 | Short (position 1) | ST-3-9 |
| 5 | Medium (position 2) | ST-4-10 |

| 1150 | Remove side coax from Face 1 of IT4. To do so first remove two round-head screws from tower side and two flat-head screws on detector side. Covered the pins with protector boards. However we won't have enough protector boards for all these side coaxes. |
