Overview

This page is for the organization and sharing of information about simulations for the Fall 2014 Commissioning data.

General Info

Discussion Items

  • Incoherent beam in bggen - simulate by moving coherent peak, check details of rate/shape (Sean)
  • Commissioning target geometry in HDDS/sim-recon (Simon)
  • Confirm that the simulation of EM background in HDGeant works for this running (Sean)
    • What gate should be used?
  • Decide which version of sim-recon should be used Tag new sim-recon version (Mark)
  • Nuclear recoil effects for exclusive modes - later studies if needed
    • Should we include effects for recoil protons?
    • Should we include other recoiling nuclei? (Carbon?)

Conditions

  • Software
    • tags/sim-recon-cs1 (provisional name)
    • tags/hdds-cs1 (provisional name)
    • JANA 0.7.2
    • CCDB 1.02
  • Solenoid @ 0 A, 300 A, 1200 A
  • Assume unpolarized photon beam 1 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
