Abstract
An arithmetic device that calculates a gain of a photomultiplier tube includes: an acquisition unit that acquires a digital signal based on a dark pulse output from the photomultiplier tube placed in a dark state; and a calculation unit that calculates a total number of electrons in the dark pulse based on the digital signal and calculates the gain of the photomultiplier tube based on the total number of electrons.
Claims7
An arithmetic device that calculates a gain of a photomultiplier tube, the arithmetic device comprising:
- an acquisition unit configured to acquire a digital signal based on a dark pulse output from the photomultiplier tube placed in a dark state;
