# 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"/>


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

While the range for the angle theta runs from 5 to 55 degrees, only generated particles that are below about 42 degrees will be reconstructed with a phi shift.

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:

This is the result of a random distribution of phi, theta, and energy.

The electron energy shows an unequal distribution

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