Optics Update

10 hours 55 minutes ago
Log Number: 4487333Logbook(s): Entry Makers: samariBody: 

We've done all of the dispersion corrections up to 4L and done a 3R Y Beta that showed some improvement in the vertical differential kicks using MQA3R07 and bringing it 8% weaker. It was in a positive direction so we might try to bring it even weaker and check the 4E harp + fopt. Currently we're blocked by SL27B19 being down.

COMMENT ON Troubleshooting Optics (DC Power)

10 hours 55 minutes ago
Log Number: 4487332Logbook(s): Body: 

Yesterday we used the dynamic signal analyzer to evaluate the output of ARC1 through ARCA for low‑frequency components. No harmonic content was observed on any supply. A minor 60 Hz peak at –67 dBV was detected on ARCA, and a 120 Hz peak at –70 dBV was observed on ARC6 and ARC7. ARC1 and ARC3 showed no measurable harmonic peaks (see attached screenshots).
The 60 Hz and 120 Hz components are consistent with normal power‑line and rectifier ripple coupling. Their amplitudes are extremely low and are not expected to have any operational impact.

Tunnel Dehumidifier Condensers Off

11 hours 2 minutes ago
Log Number: 4487326Logbook(s): Entry Makers: moserBody: 

Facilities has turned off condenser sections of the following tunnel dehumidifiers that were previously ON:
* 999-DH-1 (at intersection of Injector Tunnel and main tunnel),
* 999-DH-2 (Exit Stair 1),
* 999-DH-3 (Exit Stair 2),
* 999-DH-4 (at intersection of storage area across from from the South Access tunnel entry),
* 999-DH-6 (Exit Stair 5).

Facilities cannot confirm the AHUs in the tunnel are really off -- upstairs labeling is a bit tricky, so access would be needed to do as much.

What they can positively ID they have turned off.
