Hall C - Called in for loss of vacuum between VBV3C20 and VBV3H04. VTP3C22A turbo pump was off and so was VIP3C22 and VIP3H02. Was able to get the turbo pump back on and pumping and the ion-pumps back on as well. After pumping for a while was able to open up VBV3C20 and VBV3H04.

Vacuum tech found turbo pump VTP3C22A tripped on an overload fault. The fault was reset, vacuum recovering, valves are now open.

We are bringing xC back into beam permit and should resume CW to the hall shortly.
