Matthew Gareau | North Hot-Cell | Development | TM3 | | Containment box door removal and swivel arm test |
First thing I entered into the NHC to install to the target kart mounting clip, and remove excess tools and materials from the hotcell
After the TM3 without a target was lowered into the NHC.
Once inside, with the use of the manipulators, I was able to remove the containment box door, place it on the swivel arm, move the arm out of the way, after the door was return to the containment box and reattached.

Isaac Earle | North Hot-Cell | Development | | | NHC gas delivery lines leak checked |
The North Hot Cell gas delivery lines (labeled 1, 2, and 3 on the hot and cold side panels) were leak checked today. 5psi helium gas was applied to each line in turn with the appropriate solenoid valve opened and a Staubli connector with plastic tubing and the leak check wand attached to the matching connector inside the cell. The end of the wand was sealed using tape. The Agilent G8601 leak detector was used on "sniffing" mode to check for escape of helium gas from all joints and connectors. With the sniffing line attached the leak detector test port pressure was 3.9E-1 Torr and the baseline leak rate was 1.7E-6 Torr*L/s. There was no response while testing all of the three lines. For all three there was a leak detector response after disconnecting the Staubli fitting, which confirmed that the lines were properly charged with helium. |

David Wang | Assembly/Bench Test | Maintenance | | | target staion vacuum pumps inspection. |
Edi and I inspected roughing pump ITM MP1, primary backup pump ITHMP1, and secondary backup pump ITHMP2. We checked oil level and color on all pumps. Refilled lubricant to ITMMP1. ITHMP1 and MP2 oil level is fine. ITH MP1 oil color is darker than MP2. But, both them are ok still. Shielding block has been restored after the job. |

Adam Newsome | Crane | Development | | | Crane pendant upgrade |
The crane pendant for the main hoist was upgraded to a FLEX EX2 style pendant by Canco Cranes. The installation work was performed by Matt at Canco, supervised by Tom Kauss, David Wang, and Adam Newsome. Installation work was performed in two phases since the initial installation did not provide adequate range and an antenna issue needed to be resolved (I2021-01-14-1, and I2021-02-16-1).
Items installed include:
- New pendant
- New antennae
- New receiver box, mounted on main crane control panel in the crane control room
The old receiver control box will be kept for some time in case there is a need to revert to the previous system for some reason.
The new system was tested by David Wang - including using the pendant at the far end of the target hall where range was previously an issue. Everything is reported to be in working condition. Remote mode is functioning as expected.

David Wang | Safe Module Parking | Standard Operation | | | TM2 and TM4 electrical check without targets. |
TM2 at SMP under vacuum. TM4 at silo. Frank and I did the tests. Everything is fine on TM4 check. On TM2, all mega test at 500V are around 200K ohms which is so abnormal. We will move TM2 to TCS and start investigation there. |

David Wang | Assembly/Bench Test | Standard Operation | | | Old resin can and 2A window RH clamp field measurement at silo. |
Old resin can: 0.5 meter 360 degree rotation above silo area, 350u sv/hr. On contact 3.0 to 3.5 msv/hr. It was replaced during 2017 winter shut down, and stored in silo since then.
2a window RH clamp: 0.5 meter, 160 usv/hr. On contact, hottest spot 3.5msv/hr, general,1.8 msv/hr.
Both of them were raise out of storage silo with TH crane. Pole monitor was used for field check. |

David Wang | South Hot-Cell | Repair | TM4 | | TM4 steers short investigation. |
Cables were disconnected for steers in containment box. The Megga measurement (500V) result from the top of the module:
Left to right: OL, left to top OL, left to bottom OL, right to top OL, right to bottom OL, Top to bottom OL. And all of them to ground are OL. No short on cables from module top to steers itself. The short should be inside the steers. It will be confirmed with directly test on steers. |
