On Friday February 15th, Aaron and I changed the evaporator 1 gloves. 

1. Each glove was rolled up and taped with duct tape into a little ball (to expel air).  T

2, The clamp ring and the o-ring was loosened up and placed to the side after swiping.

3. A large, clear plastic bag was taped around the each glove before taking it off.  The area around the port was swiped and no counts were found.  

4. The old gloves were placed inside the plastic bag and disposed into the contaminated waste yellow drum inside.

5. Proceeded to install new glove. 

6.  Have other spares available in the  cold lab.

Friday, February 14, 2025, 14:16: Epilog laser cutter operates. OK.

Blower, red dot, adjustments settings ok. Laser used to cut Ta foil. OK.

SN 05.6010 / 03005: Inspected. Ok. 

SN 05.6000 / 00365: Currently disassembled / out of service. (Under Process status until repaired, re-assembled, inspected, & tested)

 Thursday, November 21, 2024, 11:46: 2 Glovebox gloves were changed. The far right glove & the far left glove. 

No contamination was found on the sealing edges of the glove box. Both old gloves were placed in bags & placed in the alpha waste bin.

Work Permit: I2024-11-21-2

Note* Changing both inner gloves is recommended later. We had considered to do both however the O2 ppm spiked after the change of the first two. We were at 185 ppm & aim to not cross 200 ppm.

Additional info:

The remaining gloves were inspected and appeared in acceptable condition.  A regeneration was performed shortly after and the gas lines, pump lines were also inspected.  This will be considered as the inspection for the current inspection cycle.

The glovebox catalyst was regenerated.  No issues.  Removed TCE and PVB from inside the glovebox.  These were vestiges from the previous UCx production process.

Ultrasonicator in Cold Lab:  The ultrasonicator cooling lines and their operation was checked.  The functionality of the probe and operation software was checked.  Visual inspection of probes and water receptacle showed good operational condition. 

Thursday, August 01, 2024, 14:56

EVAP1:  Checked seal and no visible deterioration was observed.  Oil level in roughing pump was good.  Circulated argon to observe functionality of the gloves and to check appropriate gas flow. 

EVAP2:  Visually inspected the connections at the back of the evaporator.  A loose connection had been observed on the previous day but fixed.  Roughing pump running well and system operational.  The door seal could not be checked but it is working properly as evidenced by the fact that the evaporator was in use. No major maintenance required at this moment.

All lines, pump, blower, were found in working condition. From a previous issue with corrosion of lines connecting pumps, it is recommended that we check the ability of the pump to achieve full vacuum during inspections.  Currently full vacuum was observed while checking.  

The nipple connecting the argon gas tank to the regulator needs replacing.  Aaron will order it.  

 Monday, April 15, 2024, 10:50: The old IDP15 RP was not pumping the antechamber down properly. An exchange IDP15 pump is loaned to us from vacuum group. Once the tip seals on it are replaced, we will swap it again.

Applicable work permit: I2024-04-12--2. Status: Returned.

I performed a regeneration of the glovebox catalyst.  I also swapped the O2 sensor as the old one had outlived its useful life.  The glovebox will be reestablishing equilibrium for a day or two.  Please do not panic if you see high moisture or O2 values, all is good.   Thanks,

Darwin

This is a belated entry.  The regeneration was performed successfully on December 20th, 2023.

This is a belated entry.  The inspection was performed on December 19, 2023.  A leak on one of the lines from the regulator (regeneration gas) was fixed. No other issues were found. 

All lines, pump, blower, were found in working condition. 

A regeneration can proceed.

 On November 10th / 11th a site wide power outage occured. Once power was restored, the Ar glove box had intermittent issues with the solenoids & blower. The blower did not start & the solenoids often got stuck or ceased operating. 

Yesterday Randy B inspected the connections to see if they were receiving enough power. It was good from the main plug-in, through to the PLC, however was dead at fuse positions 3 & 4 on the rear panel. Both fuses were changed, but that did not help. We did some fidgeting in the back & the solenoid function returned. It was left overnight.

Thursday, November 30, 2023, 08:30: <- Approx. Initial check: Dropped a crumpled Kimwipe inside the glove box to check for air flow / blower function. It did not move. Blower was not functioning, but the solenoids did. De-energized the glove box completely. 

Removed the old corroded fuse holders, added a pair of modified new ones. Cleaned a couple of corroded critical connections. Installed the new fuses, re-plugged it back in. Function returned to normal. The Kimwipe was also moving, verifying the blower is again operational. 

Thursday, November 30, 2023, 09:51: Complete. 

Evap1:  Cleaned and checked seals.  Oil level could not be clearly determined, but are consulting with pump group to check.

Evap2: Cleaned and checked seals.
