Nominal Settings
- When starting a shift, it is prudent to verify that the magnets are set correctly. If it's not right, consult the RC. Currents should be within about 0.5 A of the values. Also, note that "readback" values are slightly different from "set point" values.
- The LHRS dipole NMR doesn't lock. Need to set manually to match the field value (iterative procedure, see the instruction below)
- Below are set points. Readbacks will be a bit lower.
Setting the LHRS Magnets
If one can not reset the magnet remotely: Do NOT go into the hall to reset by yourself. Contact RC and then tech on-call/magnet expert. Regulators for Q1, Q2, Q3 are always OFF. Q1, Q2, Q3 magnets will be set by current.
