Abstract

Accurate gain calibration of photomultiplier tubes is crucial because their fundamental function is to detect photon counts under low-light conditions. Traditional photomultiplier tube calibration methods require assumptions about the single photoelectron response in the charge spectrum, which are then used to construct the complete photomultiplier tube response function. However, discrepancies between these assumptions and actual single photoelectron responses can introduce calibration bias. This paper presents a novel method utilizing a joint analysis of charge and amplitude spectra. This approach enables precise calibration of the photomultiplier tube gain and provides an authentic single photoelectron response.

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
