Abstract
A method for real-time processing of a pulse pile-up event comprises the following steps of: generating a fitted baseline value lookup table and a fitted energy value lookup table for a pulse falling edge, using a multi-voltage threshold sampling method to identify piled-up pulses and trigger a procedure of processing pulse signals; and using pulse priori information and acquired pulse information to acquire information of an incorrectly sampled portion due to a pulse pile-up by looking up in the tables, so as to recover information of the pile-up pulses in real time. First, in the disclosure the multi-voltage threshold sampling method is proposed to identify pile-up pulses at a high count rate and trigger a procedure of processing pulse signals. Next, pulse priori information and acquired pulse information are used to acquire information of an incorrectly sampled portion due to a pulse pile-up by looking up in the tables, to recover information of the piled-up pulses in real time. The method according to the disclosure is simple, highly efficient, can be realized easily in a real-time data acquisition system of a detector level, and is still capable of achieving a preferable effec…
