This work marks the first use of a fully digital trigger system and new CAEN V1724 digitisers to create a Compton camera from two semiconductor double sided strip detectors. The system was designed to be able to identify and locate gamma ray emitting radionuclide within an energy range of 60 to 1408keV. Compton images were produced at AWE Aldermaston and the University of Liverpool across an energy range of 80 to 1408keV, using point sources, extended sources and also including special nuclear materials. The image at 80keV is the lowest recorded energy for a Compton image using a two detector cryogenically cooled Compton camera. GAMOS simulations have been used to check the experimental data and provide evidence that indicates if pulse shape analysis was applied to the experimental data the image resolution would be improved by up to 4mm at 662keV.
