Abstract
Imaging of 7 rays with 1 ~ 5 MeV with a xenon time projection chamber (Xe-TPC) has been simulated with the GEANT4 code. The clear image of a 7-ray source was obtained using the Xe-TPC. The dependence of angular resolution and imaging efficiency on xenon density were also investigated over the density range from 0.06 to 0.18 g/cm3. It was found that a Xe-TPC is promising for imaging of high-energy 7-rays (~ 5 MeV) on planetary surface.
