    Abstract

    In this study 2-dimensional plasma simulation code was used to find a new approach of x-ray detection method with PDP-like geometry and condition. A conventional PDP geometry consisted of three electrodes was selected and Ne-Xe composition gas was filled the cell-gap. Depending on incident X-ray energy, the number of charges generated within the cell-gap could be different. For the charge amplification and collection of charges two consecutive ac pulses were applied to scan and address electrodes. The increased charges were collected on the positive-bias address electrode at the rear panel. Two parameters, such as amplitude of collected current and formation delay of collected current, were calculated and compared. The formation delay showed more accurate relationship than the collected current amplitude.
