Two Photon Exchange (TPE) Experiment at CLAS

The ratio of the Electric (G$_{E})$ and magnetic (G$_{M})$ form factors of the proton measured by Rosenbluth Separation and Polarization Transfer methods differ by a factor of three at Q$^{2}$ of 5.6 GeV$^{2}$. The real part of the Two Photon Exchange (TPE) amplitude in lepton-proton elastic scattering is expected to explain this discrepancy. The ratio of elastic positron-proton to electron-proton cross sections is the only way to measure this real part. We will measure this cross section ratio using a mixed electron-positron beam in CLAS at Jefferson Lab. In this talk I will present how the electron-positron beam is produced, the backgrounds that limit our luminosity and the simulations used to reduce those backgrounds.
