  • Setting the Calorimeter angle (SMHS carriage):
    • NPS Survey Results
    • SHMS angle (as defined in magnet gui) = Desired Calo Angle + Offset
    • Average offset 16.289 deg.
    • To set SHMS angle, use universal offset 16.27 deg. Corrections can be made in analysis
    • Setting the SHMS to angles less than 28 deg (NPS < 11.7 deg) requires tech support and two people in the hall
  • FermiLab Pub-97-092 on R4125 PMT performance (including lifetime)
