Theory Frame Moller CM Frame
Figure 3a: A plot of the number of Moller scattering angle theta in the center of mass frame versus the theoretical differential cross section. The width of the bins is 0.001 degrees for the angles in the center of mass frame corresponding to angles of 5 to 40 degrees in the lab frame. A weight has been assigned for each value in theta which will give the theoretical differential cross section when applied.
Theory Lab Frame Moller Frame
Figure 3b: A plot of the number of Moller scattering angle theta in the lab frame versus the theoretical differential cross section. The width of the bins is 0.5 degrees for the angles in the lab frame. A weight has been assigned for each value in theta which will give the theoretical differential cross section when applied.

Lower Angle Theta Moller Electron Scattering in DC
Figure 4a: A plot of the number of Moller scattering angle theta in the lab frame versus the scattering angle phi. The width of the Theta bins is 0.1 degrees in the lab frame within the range of 0 to 6 degrees. Similarly, the width of the Phi bins in 0.2 degrees in the lab frame within the range of -30 to 30 degrees. Only electrons that would have fallen within the range allowed by the DC endplates have been included. Only the DC is simulated with endplates of Tungsten steel.
Theory Lab Frame Moller Frame
Figure 3b: A plot of the number of Moller scattering angle theta in the lab frame versus the scattering angle phi. The width of the Theta bins is 0.1 degrees in the lab frame within the range of 0 to 6 degrees. Similarly, the width of the Phi bins in 0.2 degrees in the lab frame within the range of -30 to 30 degrees. Only electrons that would have fallen within the range allowed by the DC endplates have been included. The clas12 setup is simulated without a target.

Moller Electron Energy vs Angle Theta in Lab Frame
Figure 2: Using the theoretical differential cross section, the distribution of Moller electrons for a CM energy of approximately 53Mev can be distributed through the CM scattering angle Theta. Using Lorentz transformations, these distributions can be transformed to the lab frame. At around 60 degrees in the lab the Moller electron has an energy of close to 1 MeV. Such a low energy does not allow the Moller electron to leave the constrains of the target where they are created.
