- We should get the information of Clamped/Reate-Limit/Quench from the Mercury-iPS to the VI
- We need to be able to ramp-down 0A with 0.5A/m rate, so there should be a preset for that.
- Need a manual override in the VI.
- We need a power-indicator on the shim power supply. These are the shim-coil-power indicators.
- We need a field indicator in the cave.
Precautions
No operation can be made when the magnet is being filled with LHe.- The magnet LHe level is so high (>20%??) that LHe remains even if soft quench happens.
- A time to ramp up/down the magnet should be planned in advance, since it takes at least 1.5 hours.
- You should remember that any deviation from the standard procedure might cause quench.
- You are expected to know what should happen at each step and confirm that it happened. You had better go through this procedure with another person who has already carried it out.
- You should search for any indication of quench during the operations, such as error messages on the magnet PS, sudden changes of Tank B, Coil T, Coil B, the magnet pressure, etc.
- You can use this chart preset: https://e906-gat1.fnal.gov/data-summary/e1039/target-par-preset/magnet_ramp.php
