Positron emission particle tracking (PEPT) is a powerful technique for studying flow inside engineering systems by tracking radioactively-labelled particles. A positron camera is used to record coincidence data arising from positron annihilation; since the precision of PEPT depends on the recorded data rate, the camera sensitivity is crucial. We report first results from a new positron camera, SuperPEPT, which has been constructed using components from CTI/Siemens ECAT EXACT 31, ART, and EXACT HR+ scanners and has a versatile geometry with a large field-of-view (FOV). These results were obtained using just two of the three detector sections but already show sensitivity and data rates much higher than achievable with previous positron cameras.
