+ Experiment E02-013 is measuring the electric form-factor of the neutron (GEn) with a double-polarization technique. Polarized electrons are quasi-elastically scattered off the neutron in polarized Helium-3 nuclei, and the final state is exclusively selected by detecting the electron and neutron.

!!!+ GEn Raw Data Structure (by Robert Michaels)
!!!!- Overview
The raw data structure recorded in the GEn DAQ datastream will be described. This includes the following data:
# Event data recorded with each accepted trigger (fastbus and VME data from the two spectrometers and from the BPM and raster)
# scalers
# EPICS information
# "special events" which are inserted once or infrequently during a run, such as prescale information and detector map.
+ This site is highly unorganized, but we are trying to fix that. Please just deal with the clutter for now.
- These data are decoded by the Podd Analyzer classes developed for GEn, see also GEn Analyzer documentation. I won't go into that here, but suffice it to say you need an up-to-date database with correct crate map and detector maps.
