“…The second consists of two distinct filters: one for estimating the pulse amplitude, the other for estimating the baseline level in time intervals where no pulse is present. Then the two estimations are summed up so that the resulting overall filter becomes zero-area, called separate BLR [6]. The last is similar to the second one; the difference is that the amplitude filter and the baseline filter perform the task of baseline restoration as a whole; i.e., the amplitude subfilter also includes some baseline correction, called share BLR [4,7].…”

Baseline shift seriously affects the accuracy of elemental analyzing when prompt gamma neutron activation analysis (PGNAA) technique is used in industry fields. Baseline is affected by signal pile-ups and environmental factors. We propose a photomultiplier tube (PMT) gating method to eliminate the effects of the environmental factors. The detector system updates the baseline before each single measurement starts. We propose an algorithm to restore the baseline shift caused by signal pile-ups. Test result shows that with the gating method, the hydrogen characteristic peak position fluctuation is reduced by half of the original value. And the resolution does not increased by the using of the gating method.
