Gain and transit time adjusting method for e.g. single-channel or multichannel photomultiplier tube, involves adjusting gains and transit time of different channels of tube to two predetermined setpoint values, respectively

摘要

#CMT# #/CMT# The method involves adjusting gains of different channels to a predetermined setpoint value, where the channels correspond to multichannel photomultiplier tube or to distinct photomultiplier tubes. Transit time of different channels is adjusted to another predetermined setpoint value. The gains and transit time of different channels are adjusted for aligning the gains and transit time on a low gain value and high transit time value of the channels, respectively. #CMT#USE : #/CMT# Method for adjusting gain and transit time of a channel of a photomultiplier tube e.g. single-channel or multichannel photomultiplier tube for positron emission tomography in medical imaging field. #CMT#ADVANTAGE : #/CMT# The method enables equalization of transit time and gain between the channels of the same or different photomultipliers in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flow chart of a method for iteratively adjusting gain and transit time.
