Alpha-Beta Probe | John Caunt

JCS is pleased to announce the new Scionix thin Alpha/Beta SiPM Scintillation detector with a built-in temperature compensated bias generator and preamplifier.

Alpha/Beta Pulse Shape Discrimination:

Features at a glance

Pulse rise time (0-100%): 150 ns (betas) & 1μs (alphas)
Pulse fall time (1/e): 1.2 μs (betas) & 3 μs (alphas)
Gain: Approx. 75 mV/MeV(betas) & Approx. 500mV /5.48 MeV (alphas)
Noise level: < 50 keV (betas) @ 22 degrees C

Uses
