AS1 was installed in the ITMY chamber today. For this I moved AS4 to its nominal final placement and clamped it down with a single dog clamp. Then, I placed AS1 near the center of the table, and quickly checked AS4 could still be damped. After this, I leveled the table using a heavier/lighter counterweight pair.
Once things were leveled, I proceeded to install AS1 OSEMs. The LL, UL, UR OSEMs had a bright level of 27000 counts, while SD and LR were at 29500, and 29900 respectively. After a while, I managed to damp all degrees of freedom around the 50% thousand count levels, and decided to stop.
UL 27000. -> 16000
UR 27000. -> 13800
LL 27000 -> 14600
LR 29900 -> 14900
SD 29500 -> 12900
Free swinging test set to trigger
AS1 is set to go through a free swinging test at 3 am this evening. We have used this script (Git/40m/scripts/SUS/InMatCalc/freeSwing.py) reliably in the past so we expect no issues, it has a error catching block to restore all changes at the end of the test or if something goes wrong.
To access the test, on allegra, type:
tmux a -t AS1
Then you can kill the script if required by Ctrl-C, it will restore all changes while exiting.
