Title:
SIGNAL PROCESSING DEVICE, ANALYSIS DEVICE, AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/181065
Kind Code:
A1
Abstract:
A signal processing device (7) processes an output signal (S0) from a radiation detector (6). The radiation detector (6) comprises a pair of electrodes to which a prescribed voltage has been applied and a gas that is present in between the pair of electrodes and that can be ionized when radiation is received. The output signal (S0) includes a peak value corresponding to the quantity of the current passing between the pair of electrodes. The signal processing device (7) comprises: a discernment unit (71) for discerning the output signal (S0) as an abnormal signal in a case where the peak value of the output signal (S0) received from the radiation detector (6) exceeds a threshold value; and a determination unit (76) for determining on the basis of the abnormal signal whether a discharge abnormality has occurred in between the pair of electrodes. The threshold value is the maximum value that the peak value of the output signal (S0) can reach when the gas has received radiation to be detected.
