PS Simulation PS Simulation

• Recent activities

– Pipeline runs

• Photons @ 0 and 40

• Electrons and Positrons @ 0

• Protons @ 0 and 90

• Pions @ 0

– First Runs in v8 (0002 – 0010 v8)

– Recent update to v9 (0011 – 0019)

– Physics update

• Same as G4Generator

– ROOT macro for reconstruction & merging with Gleam merit

– Dump cuts (1 cm)

– Energy dispersion (1%) – for hadrons?

– Beam Spread (Gaussian 0.5 cm sigma)

– Beam Divergence (2 mrad)
