| Magnet PS | We should get the information of Clamped/Reate-Limit/Quench from the Mercury-iPS to the VI. | Kenichi | Magnet PS | We need a power-indicator on the shim power supply. These are the shim-coil-power indicators. | Completed:HarshaKenichi | Not testedFirst design a proper hardware setup. | |
| Magnet PS | We need a field indicator in the cave. | Anyone? | 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 | Make auto switching through each NMR channel. | 90% | Add switching parameters. | ||||
| PDP | Remove unused parts of the VI. | ||||||
| PDP | PDP | Add calculators for TE | Completed | Implemented in data summary page. | 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 | Once we have the UVA PDP made to our needs we need to do that same type thing for the LANL system so we can use it. | ||||||
| New VI | Make a set of VIs for RF modulator, R&H xyz. | Farooq/Dustin | |||||
| New VI | Make a set of VIs for RF modulator, Agilent xyz. | Farooq/Dustin | |||||
| Heat tape | Test the RS-485 communication with the power controller (Fuji Electric PXF4). Create a VI(s) to read the present status and change the set point. | Chatura | |||||
| New VI | Make a set of VIs for Pfeiffer Vacuum OmniControl 200. | Farooq/Kenichi |
