Description

CZT Scintillator Detector from X-Z LAB is a pixelated semiconductor array for direct gamma-ray detection. Gamma rays enter the cadmium zinc telluride crystal and convert straight into electron-hole pairs — no scintillation step in between.

How the CZT Scintillator Detector works

The freed electrons and holes drift toward positive and negative electrodes. As they move, they induce electrical output signals. Because the conversion is direct, the energy information remains accurate. The effective atomic number is 50 and the density is 5.8 g/cm3, which gives strong stopping power in a thin 15.0 mm slab. Room-temperature operation needs no cryogenic cooling.

Why direct conversion wins

Skipping the scintillator removes one conversion loss. Therefore, more of the gamma energy reaches the electronics as signal. High volume resistivity keeps leakage current low, which protects the energy resolution. Gold electrodes make reliable contact to the crystal.

CZT Scintillator Detector formats and specifications

Area arrays and linear arrays are both available. The standard detector measures 22.0 x 22.0 mm2 with an 11 x 11 pixel array. Pixel size is 1.38 x 1.38 mm2 on a 1.88 mm pitch, with gold electrodes. Volume resistivity exceeds 1e10 ohm-cm. The energy range spans 60 keV to 2.6 MeV, with resolution better than 4% at 662 keV (22 C). Working temperature is -20 to 40 C; storage is 10 to 40 C.

Typical applications

Medical imaging uses these arrays where compact room-temperature detectors matter. Homeland security teams use them for screening. They serve industrial process control and food inspection lines.
