For the week of November 7th 2011, four of a possible ten targets that are in storage were assayed. Targets are as follows:
Target General average field @ 1 metre from edge of pail
SiC#24 1.99 mSv/hr |

Spent target assay completed. A total of 16 target were looked at, 13 were low enough to be assayed and those 13 are at shippable levels, the other 3
of the 16 looked at were too hot to ship and assay. See attached pdf for complete details. |

Ten targets have been assayed or had field measurements(they were too hot to ship but were assayed the last time an assay was done) done on them
over the past two days. Of those that have been assayed we have total of ten shippable targets. See the attached PDF for the latest details of the storage
vault. |

The spent target assay was aborted today after the first target was finished due to the very old computer that controls the camera and the vault
door effectively died. The vault door had to be closed using the emergency door closing winch which worked so it passed that test. |

|
The linear actuator used for the Y-motion motor assistance on the spare telemanipulator was replaced and tested. It was observed around September 2021
that the former one which was installed was causing fuses to blow for the main 120 VAC power supply in the control box. After some troubleshooting, it
was determined that the linear actuator itself did not operate smoothly - it was suspected that this caused motor overload due to additional friction. |

|
Update 2024-09-12: C. Fisher confirms this is actually normal behaviour. The Y-axis motion is inhibited when X and Z
are in a certain configuration, which was true when the manipulator was mounted on the wall in storage position. Non-issue. A note about this has been
made in the operator manual. |

Today (Wednesday July 18th) at around 4:15 pm I was taking a small tour group from VECC into the Target Hall. In the process of discussing the mechanical
design of the Target Modules and South Hot Cell turntable I inadvertently lifted the Aluminum Hatch Cover of the Hot Cell about 2 inches in an effort
to explain something. This tripped the ventilation alarm before I realized what I was doing. I evacuated the visitors from the Target Hall, checked |

At the end of manipulator repair Thursday the ventilation pre-filter in the hot cell was changed. Old filter remains in the hot cell until such time
as it can be removed. |

I have moved the suspected "hot" items in the hot cell and placed them under some lead bricks. I have re-measured the fields and it has been
reducded to 90 uSv\h at the manipulator repair area and 110 uSv/h at the previous 1.82 mSv\h area. |

|
The handle cable on the east manipulator of the south hot cell has been replaced. Old cable showed signs of wear but had no broken strands. Manipulator
is back together but still needs to be re-tensioned. |

Entered hot cell to preform replacement of slave tong cable. Existing cable shows no signs of wear so it has been re-installed. A spare tong cable has
been loaded into a spare tong while in the hot cell in preparation for next time this cable needs to be replaced. |

Two minor chips in the main 60 kV insulators on the source tray was inspected today by Anders, Tom and Aurelia. The chips are small enough that
they should not be a problem. See photos for details. |
