SEPTA
- There is no regulator on the septum magnets. You must set each one manually to match the spectrometer dipole setting.
- Use Septum Right Controls and Septum Left Controls. DO NOT USE Septum Ramp Controls.
- Type "~adaq/bin/GetSeptaCurrent <P0>" on any adaq machine to calculate the necessary septa current.
SPECTROMETERS
- The correct “tune” for the spectrometers is “g2p/Gep_1” which you’ll see on the regulator controls page (The button to the right of GeV/c after the P0 set box). This determines the quadrupole and dipole settings for the spectrometer proper.
- Make sure the regulator is ON during normal running.
