MULTICHANNEL DETECTOR HAVING A REDUCED NUMBER OF OUTPUT CHANNELS

摘要

The present invention relates to a multichannel detector having a reduced number of output channels, and including: a linear amplifier for linearly amplifying an input signal; an offset correction unit including a circuit separated from the linear amplifier and an operational amplifier therein, and configured to correct the offset level which varies according to the amplification rate of the operational amplifier; a uniformity correction unit for reducing the irregularity of an input signal by minutely adjusting the gain of an output signal from the linear amplifier; a signal delayer for delaying the output signal of the uniformity correction unit until an output signal is generated from a comparison unit and a signal determination unit, and a switch circuit receives a trigger from the signal determination unit; the comparison unit, which compares the output signal of the uniformity correction unit with a signal of a predetermined level; the signal determination unit, which determines the position information on a channel where an event occurs by receiving a trigger signal from the comparison unit, transmitting the trigger signal to the switch circuit of the determined channel position, and outputting the determined position information; and a unit for processing the channel information, which receives energy information, time information, or position information on a channel where an event occurs once a trigger signal is inputted to the switch circuit of the determined channel position from the signal determination unit. In addition to the position information on a channel where an event occurs and to the energy information, time information may be further provided by using an additional clock generator and signal determination circuit.
