Title:
エネルギー測定装置、エネルギー演算装置、エネルギー測定方法並びにエネルギー演算プログラム
Document Type and Number:
Japanese Patent JP7368783
Kind Code:
B2
Abstract:
A target that is irradiated with a charged particle to emit a neutron, an output circuit such as a DC/DC converter that includes a semiconductor element and that outputs voltage during normal operation, and a counter that measures elapsed time with a point in time when the neutron is emitted from the target defined as a starting point are included.Furthermore, a measurement unit that measures the voltage output from the output circuit, and a calculation unit that calculates time of flight of the neutron based on a time when a measurement voltage value measured by the measurement unit falls below a predetermined threshold value and the elapsed time measured by the counter and that calculates energy of the neutron based on the calculated time of flight are included.
