0T Solenoid

The commands used in GEMC to create a uniform spread of electron energy across the solid angle of the detector:

 
<option name="BEAM_P"   value="e-, 6.0*GeV, 30.0*deg, 10*deg"/>
<option name="SPREAD_P" value="5.5*GeV, 25*deg, 180*deg"/>

Gives a uniform distribution across the solid angle components, theta and phi:

The change in Theta shows the effects of the Torus re-orienting the Moller electrons toward the beam line.

The Phi distribution shows the 6 different paddles of the the detector.

Looking at the relationship between the scattering angles theta and phi:

The electron energy shows an unequal distribution

Electrons of energy around 2GeV are more easily influenced by the torus magnetic field.
