Suggest an appropriate gain of the MCA amplifier
i sketched the displayed spectrum... also looking at the solutions they somehow got a gain of 2*10^3 with the pulse height of 4.0 mV at a channel 409 corrresponding to 8 V.
any ideas how htey got that gain and the channel number corresponding to the pulse height?
i tried fiddling round with the formulas given of
energy resolution = (FWHM / pulse height at centre of peak) * 100%
no luck.. somehow they got a gain of 2*10^3 for a plot that is num of counts vs channel number...
hope you guys know
