Tasks in Hall
- Which are most urgent? Kenichi should work on them before moving to Japan on Aug. 31 (We).
| Date | Category | Task | Status | Note/Question |
|---|---|---|---|---|
| Magnet | As soon as you can please check all the materials I sent about the shim power supply and try to figure out what the output voltages should be and to what set of pins so we can check that all is working. You may have to piece this together from a few of those sources but I believe what you need is in there. Once you have that let's check that we are getting what is expected and then make a quick and easy reference of this information and so details about how to check this in the future. | Steps:
| We will try another way of test when finding it. (We need to gather what information we have and make an updated version of the drawing Carlos/Zulkaida made with where each of those leads connects and the voltage they should carry, we should organize this information soon to help with trouble in the future, we will have cooldown soon, priority 1). | |
| LN2 | The sensors on the nitrogen piping (to the cave) are not represented anywhere in the system. These will need to be added somewhere like the cryo control panel. We may already be able to get this information from the QT data stream from the ODH PLC. | Done. LL106-N and PT106-N were added to the QT Overview screen. | ||
| Temp. | We also need the sensors from the chilling water from both the NMR system and the microwave system to be in the cryo control VI with some graphics to indicate what it is. There is more information from the flow of the chiller that should also be indicated. | Steps:
|
| |
| Insert | We need to have a least one target insert complete with sensors and a dedicated LakeShore which is read out in the proper location in the VI. In those insert sensors, we need at least one calibrated Cernox. You may have to install that one but I can show you where it is. The other sensors can be vishay chips. | Kenichi - software Ernesto/Dustin - Insert setup priority 2. | ||
| Cable | Please make the two backup cables we need one for the fridge and one for the target insert and install. I think you said we had short cables already, so let's set up a test station for the insert with a LakeShore for the target insert in the counting-house target work area. | Steps:
| Yes making the backup cables for Fridge and target insert are priority 1. If small cables are made set up station in counting house for insert testing, also priority 1. | |
| Pfeiffer | Also, my conclusion on the magnet IVC pressure gauge is that we should buy another one and install it by the turbo. This is the best backup option I believe. Please go ahead with that. | Steps:
| priority 1. By Zulkaida. | |
| Pfeiffer | Also, the gauge on the magnet pump out, Channel-4 of maxigauge is not working. We should check the Separator one too and replace all that are needed. | Replace the two once receiving the new sensors. | priority 1. I think we can replace this one right now with the tube one. | |
| CCP | Please change all the subvi button names on the right from the device name to a functional name (I can help if needed). | Steps:
Are these abbreviated names good enough for shifter? Or do we need them in the pop-up message on each reading? | MKS 670 / 1000 → Fridge Pres. / 1000 MKS 670 / 100 → Fridge Pres. / 100 MKS 670 / He3 → He3 Pres. MKS 946 → Main Ret. / Ret. Mani. Pres.

| CCP | Need graphic for NMR/microwave water and flow | Set up the hardware first. | priority 2. | |
| CCP | Organize temps on the fridge at the proper location for each digital field | Done. Move the digital fields. | priority 3. | |
| CCP | We will need fridge valve actuator info read out to the field when we get it (can't do now). | Set up the hardware first. | priority 3. | |
| CCP | Change all LN2 and LHe temps to Kelvin | Done. | priority 3. The unit has not been changed for the temperatures that are expected to be around room temperature (like the fill-line surface temperatures). | |
| CCP | Add in other LakeShore for Insert temps | priority 2. | ||
| CCP | Add graphic for QT compressor temps and put temps in | priority 2. | ||
| CCP | add magnet coil graphic with both sets inner-4 and outer-8 | Steps:
| priority 1. | |
| CCP | fix purity graphic (it bypasses oil trap but not filters) | Done. | priority 3. Fixed in schematic version 6. | |
| CCP | roots temperatures read out with other roots sensors (will have to calibrate) | HMI shows temps | priority 3. | |
| CCP | make fridge level probe graphic indicating level | Done. | ||
| CCP | make level probe graphic for LN2 and LHe for the magnet. | Add them to the Main panel. | They are available in the magnet VI. priority 2 | |
| CCP | Once we know where the nitrogen pipe sensor is being read out lets put a version in the VI. | priority 1, I am working on this | ||
| CCP | Show the outdoor relief pipe of that magnet in the VI. I think we will need a temp sensor here. | Set up the hardware first. | priority 4. | |
| CCP | Add a function to THCD-400 to close (not only setting flow to 0) the flow controllers. | Done. | priority 1. | |
| Alarms | Set up critical alarms for cryogenic monitoring | Ishara/Kenichi | |
| Fridge | Setup run valve to be fully operational from counting house (check with backfilled separator to fridge flow) | Vibodha/Kenichi | |
| Fridge | Setup remaining fridge parts (u-tube cup, sep relief valve,..) push for final walkthrough | Vibodha/Ishara | |
| Turbo | Get large Turbo working and tested | Farooq/Zulkaida | |
| Insert/CCP | Setup target insert with one Cernox, and chip resistors on cups and read out in cryocontrols | Ernesto/Kenichi | |
| Insert | Finish construction of both target inserts | Ernesto/Farooq | |
| CCP | Implement PID control for the magnet return flow on the magnet dewar pressure. | Kenichi |
