Simulation study on unfolding methods for diagnostic X-rays and mixed $$gamma$$ rays

A photon detector for unfolding X-ray energy distribution has been previously reported. Simulation studies on the unfolding method for this detector are discussed for diagnostic X-rays and mixed-source $$gamma$$ rays of $$^{137}$$Cs/$$^{60}$$Co. Response functions for diverse diagnostic X-rays are almost indistinguishable and an unfolding using error reduction method is not sufficiently worked. The spectrum surveillance method is effective in this case. However, a simple error reduction method is useful for mixed $$gamma$$ rays. For both techniques, the neural network method is promising.

We evaluated the neutron-detection characteristics of a cryogenic neutron detector operating at 1.6 K, which comprises a liquid helium-3 as a neutron converter and an InSb semiconductor detector. The InSb semiconductor detector detected the protons created in the nuclear reaction $$^{3}He + n rightarrow p + T$$ in the liquid helium-3, where the density of that is ~600 times larger than that of the gaseous helium-3 at room temperature.

Cryogenic neutron detector by InSb semiconductor detector with high-density helium-3 gas converter

The neutron-detection characteristics of a cryogenic neutron detector comprising an InSb semiconductor detector and a helium-3 gas converter were evaluated at a gas pressure of up to 12.5atm at 4.2K. The detector successfully detected stable neutrons under these conditions, where the density of the helium-3 gas is a few-hundred times higher than that at room temperature. It was found that the neutron detection efficiency was correlated with the gas pressure - even in a backward-detection configuration - in low-temperature, high-pressure helium-3.

We evaluated the neutron-detection characteristics of a proposed cryogenic neutron detector comprising an InSb semiconductor detector and a helium-3 gas converter. The neutron detector was operated at 4.2 K with helium-3 gas filling up to 1.5 atm, at which the density of the helium-3 nucleus corresponds to that at 160 atm at room temperature. The secondary particles generated by the $$^{3}$$He(n,p) T reaction were successfully detected by the InSb detector with a time response of $$sim$$80 nsec at all tested gas pressures.

Undoped-type InSb radiation detector with rapid rise time

Radiation Detectors and Their Uses, p.113 - 117, 2003/00

We fabricated the schottkey-type InSb semiconductor radiation detector using an undoped InSb substrate, and evaluated the charactersitics of the alpha particle detection. The InSb detectors detected alphar particles successfully at all the tested temperature from 4.2 to 115 K. The 10-to-90% rise times of the preamplifier outputs were about 350 nsec regardless of the operating temperature. These fast rise times were about 20 times improved comparing to those from p-type InSb semiconductor detector.
