|---|---|---|---|
| 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 |
