ABSTRACT:
A capacitive transducer which converts impulses of absorbed energy into impulses of electronic charge, combined with a unity-gain, non-inverting amplifier and an integrating capacitor which is substantially smaller than the transducer capacitance, further combined with a transconductance amplifier, comprises a simple and compact radiation detector probe. The detector probe, connected to a signal-receiving assembly through a shielded cable, comprises a useful apparatus for detecting and amplifying weak impulses of energy absorbed from X-ray photons, gamma-ray photons, or nuclear charged particles.
