Abstract
An alpha counting system has been designed which gives counting geometry of nearly 4π with resolution capabilities of 25 keV or better. The alpha source is electro-deposited onto a thin gold foil which is sandwiched between two silicon surface barrier detectors. Alpha pulses from the two detectors are amplified, normalized and summed as a single pulse height spectrum. The techniques for the electrodeposition of the alpha activity onto the thin gold foil are described.
