The beam blockers for M9 and M20 were actuated, and vacuum was monitored to ensure no disruptions. Both actuation tests were successful. Motion was observed and no abnormalities noted. Cabling and air connections checked: OK.
Note: there was a safety interlock issue with M9 which prevented actuation - a relay or fuse was temporarily removed from the safety system ~10 years ago but it was not replaced. It was replaced for the purpose of this test, and then removed again. |
