Abstract
An inexpensive, sensitive pyroelectric bolometer for use as a fast neutral beam detector is described. Experimentally determined responsivity and noise equivalent power are presented, and are shown to agree with theoretical predictions. The detector has been used to measure the power absorption coefficient and the secondary electron ejection coefficients for 150 eV to 10 keV hydrogen and helium atoms impinging on a silver surface.Keywords
