Selection, through the PUR, of a time window of the CSP waveform for the slow shaping. Each selected time window is termed `Snapshot', while the width of this window is termed `Snapshot Time' (ST). The selection is related to the reference time of each fast SDL pulse: a pulse is accepted if it is not preceded and not followed by another pulse in the ST/2 time window periods; if two detected fast SDL pulses are within ST/2 of each other, then neither pulse will be selected. The PSHA is performed on the snapshot window with benefits at high ICRs (minimization of baseline shifts, etc.). The pulses represent X-rays from an Ag-target X-ray tube impinging on a semiconductor detector (CdTe detector) with an ICR of 2.2 Mcps. A ST of 2 µs was used. |
