Services completed today. There are still some teething pains, particularly the arc p/s as noted earlier. But we did have some beam on around noon for the first time, using neon source gas. Plan is to install helium source gas at the last minute, after all other checks, particularly leak checks, and a background calibration are done.
Later... IOS:BP1 made some clanking noises about a half hour ago, something like a car I used to own. Pump vacuum bumped at the time. See stripchart below. Quiet now, and pressure okay. ICR is keeping a watch.
Later... I closed off the source gas hand valve at 18:00 for the night, in case the scroll pump breaks and ICR has to shut down the turbos, etc. |
