Identification and correction method of nuclear detector pulse forming pile-up

Identification and correction method of nuclear detector pulse forming pile-up

Gaussian forming has good time, response and SNR, Gaussian shaping is widely used in nuclear signal processing because of its simple realization and good comprehensive performance. When working in high counting rate environment, the output pulse signal of nuclear detector often appears pile-up pheno...
