On June 2 2022, while attempting to install target SiC#42 a gasket fell off the water line. I attempted to remove the target to have the gasket reattached,
however the multi pin connector guide pin was loose and was preventing the target from being removed. During the attempt to remove the target it was noticed
that an electrical cable in the back of the module had become loose and was dangling. The target was then secured to the module, and then the module was |

While removing the SiC#42 it became apparent that the multipin guide pin had become loose
again and was not allowing the target to dismount from the module.
The multipin shoulder bolts were removed and then the multipin was able to be pried off. |

Myself and Maico were able to top up the NHC window oil.

Today while I was removing the SiC#43 it was noticed that the multipin guide pin was loose.
This made it difficult to remove the target, and the multipin shoulder bolts removal was required.
With the loose pin it was not possible to attach the multipin for the target C#4. |

Cleaned top of the ITE vacuum flange and top of window clamp. Attempted to clean the bellows/beam pipe through the wall, mostly dust and small particles.
When cleaning bottom of the wall penetration we picked up a stone/fragment and the vacuum stopped. Appears to be a rock of some kind. 800cpm.

Continued with vacuuming inside wall penetration to remove debris. Changed filter bag in nilfisk vacuum, left old filter in place however vacuum continues
to stall after >5min use. Vacuum gets quite warm before self shutting off. Debris seems to be falling back down on to joint if vacuum is turned off.
Took some screenshots of video showing removed debris and rust(?) on beam pipe. Video located on remote handling group folder. |

R. Kuramoto and A. Laxdal measured the distance from the 2A tunnel to the tank flange of ITE. The new fabricated beam pipe with bellows was used to gauge
the distance to the tank flange; The flange face of the beam tube was butted up to the tank flange and the beam tube was marked at the plane of the wall.
A metal rod was used to gauge the distance to the tank face using the same method. |
