The Wide-Angle Compton Coincidence (WACC) technique was adapted to measure the electrons produced in cadmium zinc telluride (CZT) detector by Compton scattered gamma rays of 662 keV energy emitted by a 137 Cs source. The measurements were carried out with a 4 × 4 pixel anode array build on a 5 mm thick CZT crystal with 1.1 mm pitch. A High Purity Germanium (HPGe) detector operating in coincidence mode measured energy of the scattered photons. The coincidence pulse height data from the CZT and HPGe detectors were recorded in a list mode. The CZT electron spectra were determined by subtracting the energy of the scattered photons from the incident photon energy. The scattering angle was determined by selecting a narrow energy window in the collected HPGe spectra. The CZT electron linearity and resolution were measured in the energy range of 100 keV-300 keV corresponding to the scattering angle range of 31°-66°.
