We present results of design and simulation of the n-substrate reverse type avalanche photodiode (APD), which internally amplifies the photocurrent by an avalanche process, with the diffusion and the epitaxial methods. We aim to develop the APD which is coupled with scintillating materials for X-ray and delta-ray detections. The purpose of this simulation(More)
In this paper, crystal growth and scintillation properties of Rb<sub>2</sub>CeBr<sub>5</sub> crystal are presented. The crystal was grown with the Bridgman method using a two zone transparent furnace. The investigation of scintillation properties of the crystal were performed under the excitation by X-ray and gamma;-ray at room temperature. The emission(More)
Among several systems from the UWGSP (University of Washington Graphics System Processor) series, two recent architectures were designed for imaging and graphics, One of them, UWGSP3, has already been completed and is being used for selected applications, while the other one, UWGSP4, is being implemented now.These two systems use parallel and pipelined(More)
