Andrey and myself were working on the PSL table today, using a pickoff of a pickoff of the main beam (adding a microscope slide to pickoff ~4% of the original pickoff) to the GC750 GigeCam.
At the time we left, we scanned the area with a beam scan and didn't see any new stray beams, and nothing in any useful beam paths should have changed. We also strung a Cat 6 cable from the control room switch out to the PSL table in the cable trays, and then above the PSL table.
Currently, its not as well aligned as it could be, and also requires a very low exposure setting, of -E 50 or so to avoid saturation. |
