Hello All, Is it possible to analyze signals/photons/pulses from a 57Co source (strength 2 microCi) using a ADC (multihit readout) with 5 GS/sec? Just to look at pulse height spectrum..also I am interested to make a coincidence counting between 122 adn 14.4 keV levels! I heared that these ADCs are used to count pulse duration of less than 20 ns. But 57Co sources emits pulses in the order of microsec. Thanks for your input. Cheers.
