Conditions

  • New tagged sim-recon release?
  • Other software versions
  • Solenoid @ 0 A, 300 A, 1200 A
  • Unpolarized photon beam <10 MHz/GeV at the endpoint

EM Background Simulations

  • What is the background rate with no target?
  • What is the background rate with various targets?

Hadronic Event Simulations

Overall hadronic rate
