Webthe full width at half-maximum (FWHM) of the logarithmic gain, measured in decibels the full width at half-maximum (FWHM) of the amplification factor the width of the logarithmic gain or the amplification factor, measured at a different level (e.g., where the gain has decayed to 1/e ≈36.8% or to 10% of the maximum gain) WebThe FWHM is expressed either in wavelength unit or in speed unit when the objective is to measure expansion or disk speeds (if FWHM is in unit of wavelength, the width in km/sec is given by c . FWHM /l, with c is the speed of the light = 3.10 5 km/s). Example, suppose that the FWHM is of 2A at 6563A, the equivalent resolved velocity is about 90 ...

WebFeb 23, 2024 · The captured spectra are nothing short of astonishing: I was able to achieve 0.4% FWHM at 662 keV without the loop-buster accessories, which is pretty close to the highest theoretically possible value of 0.3%. P.S. It is possible to feed the preamp output directly into the MCA-PRO16 bypassing the shaping amp. In this case the PulseCounter ... WebOne very common mistake when calculating spectral resolution is to overlook the fact that in order to determine the FWHM of a peak, a minimum of three pixels is required, therefore the spectral resolution (assuming the Ws = Wp) is equal to …

(FWHM). For NaI(Tl) scintillation detectors, the convention adopted is to define the resolution as the relative FWHM of the 137Cs 662 KeV photopeak. Hence, the resolution will be the FWHM divided by the position of this
