A sparse architecture low power gated integrator for use with germanium gamma-ray spectrometers in remote geochemistry measurements

“…Consequently, the b~listic deficit, which is the loss of pulse height at the output of the pulse shaping amplifier due to rise time fluctuations, can be a major source of spectral broadening. For instance, if a gamma-ray line at 5Me V is measured with a 6cm diameter detector and a 6th order pseudo-Gaussian pulse shaping amplifier operated at a peaking time of 8us, the ballistic deficit causes 2.6ke V of spectral broadening [2]. If the intrinsic resolution for this detector is 3.1keV at 5MeV then the ballistic deficit contribution is obviously significant.…”
