Abstract
A nuclear reaction detection device includes an FPGA (Field Programmable Gate Array) 100 which is arranged in an environment in which particle radiation is incident, and includes a user circuit 101 configured to output a value different from that in a normal state, if an SEU (Single Event Upset) occurs in a semiconductor element included in the FPGA, and an SEF detection unit 210 which detects that an abnormal operation (SEF) has occurred in the user circuit based on the output value from the user circuit 101 of the FPGA 100.
Claims7
A nuclear reaction detection device comprising:
- an FPGA (Field Programmable Gate Array) that is arranged in an environment in which particle radiation is incident, and includes a user circuit, the user circuit being configured to output a value different from that in a normal state, if an SEU (Single Event Upset) occurs in a semiconductor element included in the FPGA;
- an abnormal operation detection unit, comprising one or more hardware processors, that detects that an abnormal operation has occurred in the user circuit based on the value that is output from the user circuit in the FPGA;
- and
- a particle energy calculation unit configured to calculate particle energy by using a time-of-flight method based on an occurrence time of the abnormal operation measured by the abnormal operation detection unit.
A nuclear reaction detection method comprising:
- a step of arranging, in an environment in which particle radiation is incident, an FPGA (Field Programmable Gate Array) that includes a user circuit, the user circuit being configured to output a value different from that in a normal state, if an SEU (Single Event Upset) occurs in a semiconductor element included in the FPGA;
- an abnormal operation detection step of detecting that an abnormal operation has occurred in the user circuit based on the output value from the user circuit in the FPGA;
- and
- a particle energy calculation step of calculating particle energy by using a time-of-flight method based on an occurrence time of the abnormal operation that has been detected.
A computer readable recording medium storing a nuclear reaction detection program, wherein executing of the nuclear reaction detection program causes one or more computer to perform operations comprising:
- detecting that an abnormal operation has occurred in a user circuit based on a output value from a user circuit in a FPGA (Field Programmable Gate Array), wherein
- the FPGA that is arranged in an environment in which particle radiation is incident, and includes the user circuit, the user circuit being configured to output a value different from that in a normal state, if an SEU (Single Event Upset) occurs in a semiconductor element included in the FPGA;
- and
- calculating particle energy by using a time-of-flight method based on an occurrence time of the abnormal operation that has been detected.
