List of Ongoing/Open Tasks
| Category | Task | Person/Progress | Note |
|---|---|---|---|
| Magnet PS | We need a field indicator in the cave. | Harsha | First design a proper hardware setup. |
| GV bypass | Need to figure out a way to fill and keep filling with the nose level over the lower heat exchanger chip resistor during DNP production mode. We need the main flow to be around 20 slm during this mode and then only way that will work is if the place where the LHe is coming from is under liquid. | ||
| Fridge valve | When the run valve is PIDing we need it to open gradually to keep the level so that the flow doesn't go too high. For bypass this is not important but for run valve we want to keep the main flow low but replenish the liquid level. Right now, this PID is making the flow shoot up and down is cycles with very high flow. | Kenichi | |
| GV bypass | The gv-bypass opens too much to get too high of flow when PIDing in pressure. It seems to open and closing a lot at large amplitude. We want this to be much more gradual and try to be conservative on delivering to much flow in spikes. The stability of the PID needs to be improved. Also, for manual control the precision of software control doesn't match the minimal step size, we should update that. | Kenichi | |
| PDP | Add calculators for t1. | Kenichi | Not PDP but data summary page? |
| Alarm | We also need either a webpage or a script that says what to do in case of each of these alarms. | Make a trouble-shooting page. | |
| PDP | Generalize the UVA PDP to be usable for the LANL system also. | Switch coil, frequency, etc. | |
| New VI | Make a set of VIs for RF modulator, R&S SMB100B. | Mohit/Forhad | |
| New VI | Make a set of VIs for RF modulator, Agilent N5181A. | Mohit/Forhad | |
| Test | Measure the DAC device (NI PCIe-6321) for the RF modulator. | Mohit/Forhad | Max frequency, etc. |
| New VI | Make a set of VIs for Pfeiffer Vacuum TPG 366 (MaxiGauge) via Ethernet. | Huma | |
| New VI | Make a set of VIs for the annealing-plate controller. | Vaniya |
Recently Completed Tasks
| Category | Task | Person | Note |
|---|---|---|---|
| New VI | Make a set of VIs for Pfeiffer Vacuum OmniControl 200. | Forhad/Harsha | |
| New VI | Make a set of VIs for the new IVC turbo pumps (Leybold TURBOVAC 1350 iR + TURBO.DRIVE 500e via Serial over USB). | Kenichi | |
| Magnet PS | Stabilize the USB cable for the photo-diode sensor system for the Shim PS. | Harsha | |
| Heat tape | Test the RS-485 communication with the power controller (Fuji Electric PXF4). | Completed. | |
| PDP | Make auto switching through each NMR channel. | Completed. | |
| PDP | Remove unused parts of the VI. | ||
| Magnet PS | We should get the information of Clamped/Reate-Limit/Quench from the Mercury-iPS to the VI. | Completed | |
| PDP | Add calculators for TE | Completed | Implemented in data summary page. |
| Magnet PS | We need a power-indicator on the shim power supply. These are the shim-coil-power indicators. | Completed. | |
| Magnet PS | Need to be able to ramp-down 0A with 0.5A/m rate, so there should be a preset for that. | Completed. | |
| Magnet PS | Need a manual override in the VI. | Completed. | |
| PDP | Import the readings of He4 & He3 pressures from CCP. | Completed. | Over TCP/IP. |
| Alarm | We need a target alarm handler that allows us to turn on or off alarms from some main GUI. We should be able to silence and initiate whatever alarms we want at any given time based on what is going on. | Completed. | There is a configuration webpage since Aug. 2023. |
| GV bypass | Add to pid on 1000/fridge pressure too. | Completed. | The 1000 sensor is used when the pressure is >100 Torr. |

Steps of VI Availability (Tentative)
- A few simple VIs for readout and configuration. It is to confirm that the device can be controlled with LabVIEW.
- A complete set of VIs for readout and configuration. Each VI should perform one function of the device.
- VIs for user interface.
- VIs for continuous measurement.
- VIs for continuous logging.
- Note that an integrated user interface (like PDP) for all the devices that we use will be considered in a future. We could use DQMH or CML DQMH.

- For the annealing system we should have the analogue setup be entirely independent of the other system, this will require 4 sensors. Two for the Waqar system and 2 for the Henery system, if possible.
- All other, ~20 sensors should be setup with the same type of DAQ that Kenichi is testing unless we determine it is not suitable regarding temperature dependent error. The error budgets are different for several of these, but Magnet coils is by far the most critical low relative error requirement. So, if it looks like this setup will work there it will work everywhere.
- Questions/discussions
- We need four of MCC E-TC, given the number of TCs at present. Can we decrease N of TCs by one or two?
- We might put one of MCC E-TC at the magnet rack, if some TCs are closer to the magnet rack than the slow control rack.

Overall Computer+Program Configuration
This section is to discuss and share the overall configuration about computers and programs that we expect. The required spec of each program might depend on this configuration.
- Target computer @ control room
- BOS/EOS/Spill-ID (which detects the hardware BOS/EOS signals to issue the software BOS/EOS/Spill-ID info)
- Cryogenic control panel (https://github.com/uva-spin/e1039-target-controls/tree/master/Cryo-Control)
- Microwave frequency calibration (https://github.com/uva-spin/e1039-target-controls/tree/master/Motor%20controller)
- VIs/projects of all standalone devices
- To be listed...
- NMR computer @ cryo platform
- PDP (https://github.com/uva-spin/e1039-target-controls/tree/master/PDP) — Misha found that the measurement accuracy varies with the number of sweeps/event. It has to be confirmed, to determine how we configure the number and if we have to change it on spill vs off spill.
- Communication between the computers
- The NMR computer needs BOS/EOS/Spill-ID in real time. What are the limits of latency/jitter times???
- If the latency of the TCP/IP communication (<1 ms inside LAN?) meets the requirement, it can be used.
- If not, probably we have to move the "BOS/EOS/Spill-ID" function to the NMR computer.
- Other components or functions??
