Large CZT Spectrum Probe

Large CZT Spectrum Probe

PAM-01C2 is a hemisphere CZT based probe in a super small size. It can detect X-ray and low energy γ-ray in a high resolution.

PAM-01C2 integrated customized CZT crystal and low noise charge sensitive preamplifier circuit. It can convert X/γ-ray into exponential decay signals. Working with five-pin cable, high and low power supply and main amplifier,those signals will be direct into multi-channel pulse analyzer and then the energy spectrum will be formed.
