“…(9) , will change with processing time constants used in the electronics and may also change with count rate. In fact some electronic processors have adaptive shaping that is designed to produce the best resolution possible for a given count rate [ 22 ]; this not only guarantees that resolution changes with count rate, but also introduces a weighted series of Gaussians with different fwhm 0 values into the peak shape model. Noise contribution to a detector may also change over time and be temporarily affected by electronic interference.…”

“…With shorter pulse‐processing times (and consequently degraded resolution) a throughput of 10–20 kHz is possible. Recently, advances have been made, such as digital pulse processing (Mott & Friel, 1995), that significantly extend the limiting counting rate of the semiconductor energy‐dispersive X‐ray spectrometer to 50 kHz. More significantly, a new class of very high‐speed EDS detectors, the silicon drift detectors, has emerged with limiting count rates of 500 kHz or more (Struder et al ., 1998).…”

“…Additional benefits have been claimed by using digital pulse processing where analogue circuitry has been replaced by digital recognition methods in which the time constants are variable. This adaptive pulse processing (Mott & Friel, 1995) extends the shaping time until the next pulse arrives, thereby optimizing the resolution for a given throughput of counts. Digital pulse processing has other advantages too, giving a more linear response than analogue shaping and also reducing deadtime further.…”
