I have re-measured the fields in the hot cell. Fields at shield door Al cover are 101 uSv\h, in cell at the east manipulator are 245 uSv\h, and the largest
field is 1.84 mSv\h...this appears to be the high current fasteners removed from the last target. |

The west 'Z' motion cable on the east manipulator has successfully been replaced. The job took slightly less than an hour (including inspection of the
scissor table hoses) and I received 0.075mSv. Scissor table hoses appear to be fine and also didn't "shed" or flake at all when checked by hand. |

Today, I checked TH crane main hoist when shielding plug is installed into ITE pit. I did some jogging actions on main hoist during the operation.
Everything looks fine. No burning smell, no strange noise. An outside crane expert suggest that jogging is the worst working situation for crane. We have
to use jogging actions during our crane operation. But, we could try to use less jogging when operate the crane. |

close during first time try. So, the smell appeared when operate the brake. He increased the gap to a proper distance then. It looks like everything works

Anders and I found a low frequency issue(13hz only) on TCS TGHT flow sensor when doing TM4 conditioning. By trouble shooting, We found the module water
lines are good. the restriction cause this problem in on TCS supply or return water lines to TGHT. I switched TGHT lines with MSP water lines. The
wheel frequency on TGHT is 67.0hz which is pretty high. Now, MSP is using the original TGHT water line(flow sensor frequency 13hz). Flow sensors and |
