Abstract

the electron tracking compton gamma-ray camera is consisted of two detectors which are a scatter detector and absorb detector. The scatter detector is a Time Projection Chamber which spatial resolution is 0.4 mm and energy resolution is 25% at 22 keV. This system can take the recoiled electron track and energy. The absorb detector which catches the position and energy of a scattered gamma-ray. This detector is consisted of GSO scintillator and multianode photomultiplier tube. A position resolution is 6 mm and the energy resolution is 11% at 662 keV. A spatial resolution of this whole system is 3 cm at 10 cm distance from detector and the efficiency is 10^-5 sec^-1 m^-2. And, we report the various kinds of images.
