SEPTA
- There is no regulator on the septum magnets. You must set each one manually to match the spectrometer dipole setting.
- Type "~adaq/bin/GetSeptaCurrent <P0>" on any adaq machine to calculate the necessary septa current.
- Use Septum Right Controls and Septum Left Controls to control the septa. DO NOT USE Septum Ramp Controls.
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.
ALARM
- HowTo Set the Septa Alarm
