ICI Detector for Measuring Gamma-Ray Fluxes in Mixed Gamma-Neutron Fields

  • A new gamma-ray detecting device called ICI detector has been developed and tested. Like vacuum Compton diode(VCD) and dielectric Compton diode(DCD) generally used in pulsed gamma-ray measurements, ICI detector operates by utilization of the Compton effect and has low sensitivity to gamma-ray fluxes, very fast time response, large linearity and wide dynamic range, it is desired for using the device to measure intense and rapidly changing gamma-ray fluxes. Compared to the existing VCDs and DCDs, the detector requires no vacuum in operation and the active volume is only 2mm thick.

Abstract: A new gamma-ray detecting device called ICI detector has been developed and tested. Like vacuum Compton diode(VCD) and dielectric Compton diode(DCD) generally used in pulsed gamma-ray measurements, ICI detector operates by utilization of the Compton effect and has low sensitivity to gamma-ray fluxes, very fast time response, large linearity and wide dynamic range, it is desired for using the device to measure intense and rapidly changing gamma-ray fluxes. Compared to the existing VCDs and DCDs, the detector requires no vacuum in operation and the active volume is only 2mm thick.
