Abstract

MCP(microchannel plate)와 지연산 양극판(delay line anode), 그리고 지연선 검출회로로 구성되는, 원자외선 분광기 에 사용될 2차원 지연선(delay line) 방식 의 위 치 검출기 (position sensitive detector)를 설계하고 그 중 지연선 검출회로를 제작하여 동작 및 분해능에 대한 시험을 수행하였다. 이 시험에서는 검출회로의 고유한 분해능을 확인하기 위하여 MCP와 양극판은 각파 특성이 잘 알려진 스티뮬레이션(stimulator)와 양극판 시뮬레이터(anode simulator)로 대체되었다. 제작된 검출회로는 안정적으로 동작하였으며 분광 및 영상 축 방향으로 각각 약 570ps와 약 100ps의 시간 분해능을 가지는 것을 확인하였다 We designed two-dimensional position sensitive MCP(mixt.ochannel plate) detector for FIMS, which is composed of MCP, delay line anode, and delay line readout elec-tronics. And also, we fabricated and tested for the operation stability and resolution of the delay line readout electronic system. An anode simulator and a stimulator were used instead of the real MCP and anode during the test to see the electronic contribution to the resolution. The readout electronics was operated stably and showed time resolution of about 560 ps for the spectral direction and about 100 ps for the image direction respectively.
