Three-Dimensional Characterizing Analysis of Astronomic CCDs with a deep depletion

깊은 공핍층을 가지는 우주항공용 촬상소자의 3 차원 특성 분석

Buried channel JET-X CCDs (Joint European X-ray Telescope Charge Coupled Devices: EEV CCD12) with a deep depletion have been analyzed to provide an optimized condition for a charge storage and transfer. A maximum charge capacity has been found for the supplementary narrow channel by considering the potential distribution as a function of a mobile charge. Analysis for the depletion edges of JET-X CCDs have been successfully performed, showing good agreement with the depths estimated from X-ray detection efficiency measurements [1]. (omitted)
