Blocks 1-4 have been moved from ITW to ITE. Block 5 was moved to a storage area as it will be in the way of the harp repair. Danka took air samples
and found 200 counts of alpha on the air samples but nothing on the swipes. It is recommended that resporators be worn while blocks are being lifted and
lowered. She will check the monitor tomorrow to confirm it is behaving as it should. |

|
Yesterday I visually inspected the paddle wheel and noticed that it was spinning freely and constant. As the signal was intermittent replaced the
coil at the back of the wheel only. This does not require access to the high active water. With the coil replaced the signal looked strong. I asked operations
to keep and eye on it and advise if the problem has been resolved. I also discussed with David this morning and he informed me that this is the same procedure |

|
The C2 circuit (coil 2) water lines and blocks have been revoed from TM4.
Water block jig could not be used as the window water block connection was nowhere near fitting into the jig (IMG_1224 image below) and
therefore caused an interference causing the rest of the blocks to not mate with the jig. A different tool that has never been used was implimented and |

There is something wrong with the BIAS canbus controller. It says that it is not alive and has timed out. I have tried unplugging it and plugging
it back in but that has not resolved the problem as it normally does. I have contacted Dave Morris and am waiting to hear from him. I cannot HV test without
this controller. |

|
This afternoon TM4 with the coil removed was tested with HV. The EINZEL LENS was first tested independently while the bias canbus was being repaired.
The current on the EL looked stable at 25kV for 5 minutes. At 27.5kV the current becomes unstable and occasionally sparks. This voltage was held for 30
minutes but the current did not appear to be becoming more stable. Further extended testing would be required to determine if this can be conditioned out. |

Maico and I leak checked HS circuit after Chad installed the target. The circuit was a little bit difficult o pump down because of residue water moister
inside. But once the moisture was pumped out, the pumping down was smooth and fast. The base leak rate 0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr.
Maico checked helium flow before the leak test. Then,He sprayed helium to all 3 VCR fiitings on target with 2 seconds on each one, He also flushed 10 seconds |
