Thursday, May 17, 2012, 13:15
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 |

Found some water tripping in front of the high voltage power supplies rack from the water lines at the ceiling. Plastic sheets have been put on top of
the racks and MCR has been informed. |

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. |

A new turbo has been installed. Eddie said the other one had crashed but not catastrophically. He recommends the test stand
be wiped clean before pumping because there is a fine layer of Aluminum dust on the chamber base.

Leak found on the Ne supply line. 1E-4 - 1E-5 range. Replaced fittings. Had to use one brass piece. Leak rate 6E-9 (probably due to Ne response). No
response to He.
Leak rate around low E-8 with regulation valve open. |
