Friedhelm Ames | | | | | | | Problems/Solutions | fluctuations in magnet current |
The current at the magnet power supply TMS:MB1 shows fluctuations every 1-2 minutes. The same can be seen in the Hall probe read back and in the beam current at Fc6. |

Friedhelm Ames | | | | | | | | source tripped off over night |
A big vacuum excursion tripped the source off at about 1am. The vacuum did not fully recover afterwards only down to about 1.3e-6T. Ne leak has been closed and vacuum went down to 6e-7T within a few minutes. After the trip the current of the magnet stayed constant. Fluctuations may have been caused by high voltage sparks. |
