| |
| Circulation test for QT |
| Dustin, Ishara | Done | Transfer-line → getting back via vaporizer is done |
| Slow Controls Rack | Lakeshore testing (We tested the hardware but only a few channel. We need to test all of 8 channels): - Test 8 channel of the readout for all Lakeshores in the counting house
- Test the LabView-VI using laptop in the counting house & decide which version of VI that we use
- Test the Lakeshores readout in the rack after the fridge/stick in place and read from the target computer
MKS 670: - Produce/purchase the cable, and install Baratron 1000 Torr sensor
- Produce/purchase the cable, and install MKS615 sensor
Purchasing (a total of ~$ 4,300 for items related to SC/magnet rack needed to be purchase: - Purchase ~$1,900 with UVA account
- Arrange other institution to purchase another ~$2,400 items
Fridge-valve control: Backup cable - Produce and install the cable or Lakeshore, AMI1700, etc after the order from Digikey arrive
- Install the cable after the order from Pfeiffer and AMI1700 arrive
Automatic Annealing backup: - Finish the labview
- Send to Fermilab and test the VI from target computer
ORC: - New Annealing box
- Final SC Rack
Working on it Waiting the cable, need to have backup plan | Waqar, Kenichi

?? | - The fridge reading was completed.
- The insert reading?
- The cable parts were delivered.
- Will assemble cables and connectors.
We have something that works
Working on it
Start work | |
| Magnet Rack | AMI1700 testing: - Put liquid nitrogen, and test the readout all the way to PLC (the AMI readout should be consistent with PLC readout)
- Test the Labview VI or browser based readout
(not urgent)
Mercury ITM: - Test the VI from the target computer
Maxigauge: - Fix the VI readout (currently the instrument readout and VI does not match)
Magnet & Shim PS: - Check the DC voltage/current on the cave side of the cable
Pressure sensor: ORC: - Final Magnet Rack
- Automatic annealing box

Waqar and Sam are working on having the readings on HMI.
Need to find variable names for LHe and LN2 levels |
| In-cave piping and other pumping | - Setting up the safety manifold to be pressure tested
- Pressure test for helium safety relief manifold
- Installing the manifold with the Rigging team
- Installing insulation for LN2 supply line
- Installing remaining gHe hoses
- Installing two relief valves (gHe safety, gN vent)
|
| Pressure test was completed for both Magnet Dewar and Manifold. |
|
| Fridge & Target stick & insert | - Install all temperature sensors
- Install heater/annealing plate + sensors
- Install Fridge in the Magnet
- Setting up He3 level probe
- Target insert test: Connect to Lakeshore to see the temperature sensor
|
| Waqar is working on fridge |
|
| NMR | - Noise test comparison between UVA & NM4
- Ask Kun what's the plan (maybe the long term plan) with LANL rack
- Preparing for 2 channels available for UVA-NMR
|
| Kun will move to other place and will switch between UVA-LANL NMR |
|
| Thermocouples (Temperature sensor) | Install MCC E-TC and sensors and testing. | Kenichi | |
|
| Microwave system | Order parts? |
| Vibodha will working on it |
|
| PLC & QT & Root | Installing thermocouples to check the LCW temperatures at the coldhead compressors' inlet/outlet | Kenichi, Sam (ACU) | - Installed all Selected the hardware.
- Received the hardware on June 28.
- Install them.
- Tested the readout using simple VI.
- Developing Set up VI.

| Cryogenic Control Panel | - Fridge, Insert sensors
- Fridge valve controls
- Need to get info from level probe
- have P&ID on screen
| Kenichi | - Can control the fridge valves already. Will calibrate parameters once hardware gets ready.
- Which level probe?
- Include P&ID when having a time.
