Cadmium Telluride Sensors for highest Quantum Efficiency

Each CdTe detector module comprises two large CdTe crystals (sensors) each with dimensions of 42 mm × 34 mm, leaving a horizontal gap of only 3 pixels between the two crystals. The CdTe thickness of 1000 µm provides high quantum efficiency for hard X-ray energies up to 100 keV (Tab. 1).
