Abstract
A method for detecting a neutron includes providing a first voltage to an input electrode of a microchannel plate, providing a second voltage to an output electrode of the microchannel plate, the second voltage being more positive than the first voltage, measuring a signal on the output electrode, and detecting a neutron based on a comparison of the signal at the output electrode with a baseline value.
Claims65
A method for detecting a neutron, the method comprising:
- providing a first voltage to an input electrode of a microchannel plate;
- providing a second voltage to an output electrode of the microchannel plate, the second voltage being more positive than the first voltage;
- measuring a first signal on the input electrode;
- measuring a second signal on the output electrode;
- and
- detecting a neutron based on a comparison of the first and second signals.
3 more elements
A method comprising:
- discriminating between a neutron and a gamma ray by using a first signal on a first electrode and a second signal on a second electrode, the first and second signals being influenced by moving charged particles generated as a result of an interaction between an incident particle or radiation and a material disposed between the first and second electrodes, the material comprising a first component that is sensitive to neutrons and a second component that is sensitive to gamma rays;
- and
- generating a detection signal indicating that a neutron has been detected when the first signal and the second signal have different polarities.
A method for detecting a neutron, the method comprising:
- providing a microchannel plate having an input electrode and an output electrode, the input and output electrodes being connected to different voltages;
- and
- generating a signal indicating detection of a neutron when, for a first period of time, a first signal at the output electrode has a polarity different from the polarity of a second signal at the input electrode.
A neutron detector comprising:
- a microchannel plate having an input electrode, an output electrode, and a glass plate comprising microscopic channels, the input electrode to be connected to a first voltage, the output electrode to be connected to a second voltage different from the first voltage;
- and
- a data processor to determine whether a neutron has been detected based on a comparison of a first signal on the input electrode and a second signal on the output electrode.
A neutron detector comprising:
