Today: did a mass scan at 580A on TGHT and 230A on TBHT at 30kV. Found some A/q units discrepancies on the mass scan page. It may be a hall probe problem:
under investigations.

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. |

After the test-stand, the EE was removed for inspection. It was discovered that there were some solid residues coated on the extraction electrode
and the common plate, but the ionizer tube was clean (see attachment#1). Some samples were collected and will try to do some analysis. This |

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. |
