| Research Abstract |
We have developed a Compton gamma-ray camera with a wide field of view and high sensitivity to develop the MeV gamma-ray band where astronomical observations lag behind the most in the X-ray to gamma-ray band. The camera is based on a new method of detecting the three dimensional track of an electron Compton-recoiled in a detector where a gamma-ray is Compton-scattered. The camera consists of a three dimensional tracker using a gas chamber and a gamma-ray camera with a pixelatedscintillator. In addition, we have developed a compact readout system with low power consumption for a balloon flight
