RADIATION DETECTION SYSTEM AND METHOD OF ANALYZING AN ELECTRICAL PULSE OUTPUT BY A RADIATION DETECTOR
First Claim
1. A radiation detection system comprising:
- a photosensor to receive light from a scintillator via an input and to send an electrical pulse at an output in response to receiving the light;
a signal splitter to replicate the electrical pulse to produce a first replicate and a second replicate;
a pulse analysis device to analyze the second replicate; and
an output control circuit to send the first replicate to an output, wherein sending the first replicate is based on the analysis of the second replicate.

Abstract
A radiation detection system can include a photosensor to receive light from a scintillator via an input and to send an electrical pulse at an output in response to receiving the light. The radiation detection system can also include a pulse analyzer that can determine whether the electrical pulse corresponds to a neutron-induced pulse, based on a ratio of an integral of a particular portion of the electrical pulse to an integral of a combination of a decay portion and a rise portion of the electrical pulse. Each of the integrals can be integrated over time. In a particular embodiment, the pulse analyzer can be configured to compare the ratio with a predetermined value and to identify the electrical pulse as a neutron-induced pulse when the ratio is at least the predetermined value.

15. A radiation detection system comprising a splitter, a delay circuit, a pulse analysis device, and an output circuit, wherein:
-
the splitter is configured to replicate the electrical pulse and to send a first replicate to the delay circuit and to send a second replicate to the pulse analysis device; the pulse analysis device is configured to determine whether the electrical pulse corresponds to a neutron-induced pulse after analyzing a shape of the electrical pulse, and to send a logic pulse when the electrical pulse corresponds to a neutron-induced pulse, and not to send a logic pulse when the electrical pulse corresponds to a gamma ray-induced pulse; and the output control circuit is configured to receive the first replicate from the delay circuit, to send the first replicate to a first output when a logic pulse is received from the pulse analysis device, and to send the first replicate to a second output when a logic pulse is not received from the pulse analysis device. - View Dependent Claims (16, 17, 18, 19, 20)
