• Geant 4 Neutron Detector Geometry (.cc)
• Geant 4 Neutron Detector Geometry 2 (.hh)
• Geant 3 Neutron Detector Geometry
• Report on Design Package of Neutron Detector
• MCEEP Generated electron-Helium Scattering Events. The preceeding file contains an ASCII file with the events from MCEEP (v3.6) at Q^2=3.4 (GeV/c)^2. Each line in the file contains 3 momentum components of the scattered electron (GeV/c), 3 momentum componens of the scattered neutron (GeV/c), and the z-position of the vertex in the target (cm). There are 1163 equally weighted events in the file. To generate the events, Andrei Semenov used the momentum distribution for 3-body breakup of ^3He by Kievsky, Pace, Salme, and Viviani (Phys. Rev. C56, 64). Radiative multiphoton corrections are included. Histrograms of the distributions can be seen here.
• Latest Scheme of the Elephant / BigHand / Neutron Detector
• Tim Ngo's and Albert Shahinyan's documentation for the geometry of the Neutron Detector
