Abstract
In this paper, we investigate our concept to develop a gamma -ray Compton c
amera out of a single coaxial High Purity Germanium (HPCc) detector. The im
aging properties of the HPGe can be realized by way of a segmented outer co
ntact and digital pulse-shape analysis. Limiting factors in performance wil
l be related to the intrinsic electron momentum in Ge and the noise in the
preamplifier JFETs. In addition to discussing these issues, we will present
experimental and theoretical imaging studies that we have done using an ex
isting segmented HPGe: the GRETA prototype detector at LBNL. (C) 2001 Elsev
