 Wednesday, May 16, 2012, 16:01, Anders Mjos, , , , , , , Problems/Solutions, Loose chip of insulator material detected 
|
A chip of insulator material was detected below the lower target insulator stand-off (attachment - left picture). The chip may come from the tube
heater insulator above (attachment - right picture). The chip will be further investigated when the target is removed. |

|
During the mass scan today it was discovered, that the mass calibration was off. Further investigation showed, that the Hall probe readings are a factor
of 1.31 lower than during previous measurements. A fault report has been issued to controls. |

Just a quick check at the Test Stand:
1. The system operational ( white out not present ) with TSH:TBHT heating in progress.
2. Started the Archivers: for Source and Optics. |
