How To Get It

  • User must set environment variable $MOTTG4DIR to /path/to/MottG4/ before using the simulation.
  • A working version is maintained on the ifarm computers CUE in the directory /group/mottgrp/MottG4
  • The current version is maintained at github for those who want the model on their personal computers. Contact Martin McHugh at for access to this repository.

How It Works

  • The Mott Polarimeter team is developing a GEANT4 model of the polarimeter.

To Do List

  • Add pre-vertex energy loss Small effect for our targets (~50 keV max in 5 um Au) according to NIST --Mjmchugh (talk) 17:54, 22 April 2015 (EDT)
  • Add primary vertex output info:
    • Scattering cross-section
    • Scattering location 3-vector
    • Outgoing polarization 3-vector --Mjmchugh (talk) 19:04, 9 June 2015 (EDT)
  • Integrate Xavier's most recent calculations.
  • Interactively change angular range for primaries --Mjmchugh (talk) 09:57, 16 June 2015 (EDT)
  • Change Random Seed handling to GEANT4 standard a la QweakSimG4. --Mjmchugh (talk) 15:36, 29 June 2015 (EDT)
  • Build Mott Physics Class (single scattering based on Xavier's data).
  • Build Double-Scattering Generator --Mjmchugh (talk) 15:35, 29 June 2015 (EDT)
