Abstract
Several INTEGRAL n-type HPGe detectors have been irradiated by fast neutron s and their degradation studied through the analysis of line shapes. The av ailability of three different fast neutron beams (5, 16 and 6-70 MeV) allow ed a quantitative analysis of the importance of the neutron energy on the a mount of damage. A comparison is made with the degradation induced by high- energy proton irradiations. Transient effects on the measured resolution ar e reported after high voltage cut-off on degraded detectors.
