Web1 de jul. de 2024 · The pulse-width, τ p, multiplied by count-rate, r, (n = rτ p) is the duty cycle (n) where the high count-rate condition is achieved for n > 0.1. In the present study, considering a finite pulse-width of 300 μs, the minimum possible count rate is 0.3 kcps. Webtechnology, these count rate limits are fairly high. At modest count rates - under a few tens of kHz - obtaining precise, accurate results from a gamma spectroscopy system is a relatively routine task. At higher rates, however, things aren't quite so straightforward.
