BSC6 AIP is Railed
BSC6 annulus ion pump railed about 20 minutes ago, there appears to be a little communication to the main vacuum volume noted on PT410B, however it may just be electrical noise due to the change reported by PT410B, very small, its changes it is not replicated by other gauges, like PT424B. Nothing to do about it right now, but we will check the annulus system ASAP.

Last Tuesday, we did some troubleshooting of the annulus ion pump, we tried to induce for the short internal to the pump to let go by hitting the pump with an object, the pump only flashed once but no good results. Likely the pump is shot, this unit was a salvaged unit that was removed from another chamber, see aLOG 68433 for more info regarding the pump.
