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.
