=====ICP #1 is down=====
// [[User:John_d|Demis D. John]] 20:08, 22 April 2025 (UTC)
The tool remains down. We did not find any "smoking gun" with the PC but did find that the PC's power supply had a non functional fan and the power supply did not test as good (granted it would still power up the PC). We will continue troubleshooting the PC issue in the morning.

=====DUV Flood: UP with new procedure=====
The new parts have been installed and the tool has been tested.

We have added a timer that interlocks the lamp power supply since some users seem to have a problem remembering to turn the tool off when finished with it. The minimum time it can be set for is 30 minutes and the max is 4 hours. You will no longer be operating the main breaker on the front of the power supply. I have updated the SOP to reflect the changes, there is a copy at the tool and on [https://wiki.nanofab.ucsb.edu/wiki/DUV_Flood_Expose#Documentation:~:text=Exposure%20System%20Spectra-,Documentation,-%5Bedit%20%7C its Wiki page].
