| Conditioned TM2 up to 48kV in ITW. Some sparks and current is not very stable. Drawing about 178uA at 48kV. |

|
PIE on TiC#6 was done in the NHC. The target assembly looked brand new when we took it out, no heating spots or deposits (pictures on docushare). Online
we measured a 400kOhm connection between TGHT-TBHT-COIL to HV common (TGHT and COIL shorted in TM2 service tray) and anode was unstable above ~300V. After
the module move and before the target removal David found TGHT-TBHT-COIL was a dead short to HV common and the anode was at 39kOhms to HV common. |

TiC #6 moved from north hot cell to spent target vault placed in pail #232 put in spot 6A and the field was 151mSv/hr when removed from the north
hot cell. See attached PDF for details about spent target vault. |

|
Yesterday and today module conditioning was done on Tm4 in ITE. This is the first ramp up after the shutdown and ITE is planned to run at high voltages
for the first weeks. The module is behaving well - went up to 40kV yesterday, stayed there for an hour, and up to 46kV today. Current draw is 113uA at
46kV. No serious sparking. |

|
When I tried to raise the anode voltage in cathode bias mode on May 23 evening, I found the target or tube shorted to HV common. Investigations in the
faraday cage today showed the same. I removed all the new electronics (resistors, gemovs, etc) from the power supply to no effect, so I disconnected the
TGHT supply and pushed it away from the busbars. There was still a short. David Frank and I then went down to the pit and disconnected everything to measure |

|
The TiC#5 post irradiation inspection was done on Wed. June 14 and Mon. June 19. This target didn't have any obvious issues but it didn't produce much
beam. The inspection revealed that the container was quite embrittled and showed significant damage, though it was not broken. The FEBIAD grid looked fine,
despite the large anode current draw (indicating that current was flowing elsewhere). The gas line looked fine though the gas injection to this target |

|
The TiC#4 target that is on TM3 was conditioned to 25kV today with the EINZEL lens at 12.5kV. There was one spark shortly after reaching 25kV that
reset the bias PS and another one after the module sat at 25kV for ~30 minutes. Attached is the strip tool data and screen shot. Prior to starting
the conditioning the power on the chiller needed to by cycled as the VFD on the fans had tripped due to a recurring inrush problem. |
