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:

  • Build the mechanics

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

  • 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:

  • Install Aux 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
  • Completed

Vibodha will working on it
PLC & QT & RootInstalling thermocouples to check the LCW temperatures at the coldhead compressors' inlet/outletKenichi
  • Selected the hardware.
  • Received the hardware on June 28.
  • Install them.
  • 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.
