Abstract

A telescope-spectrograph employing a photon-counting microchannel plate (MCP)-CODACON detector has been built, tested, and flown on a sounding rocket. The detector uses a curved-channel MCP proximity focused onto a coded anode array of 1024 channels spaced 25.4-mm center to center. High quantum efficiency is obtained by depositing a cesium iodide photocathode on the front surface of the MCP. The instrument has obtained an ultraviolet (1500-1800-A) spectrum of Jupiter with a spectral resolution of 8 A, which is higher than that of any previously reported observation in this wavelength range.

摘要

一台采用光子计数微通道板（MCP）-编码孔径探测器的望远镜光谱仪已制造完成、经过测试并搭载探空火箭进行了飞行。该探测器使用一个弯曲通道的MCP，其近贴聚焦在一个1024个通道的编码阳极阵列上，通道中心间距为25.4毫米。通过在MCP的前表面沉积碘化铯光电阴极可获得高量子效率。该仪器已获得木星的紫外（1500 - 1800埃）光谱，光谱分辨率为8埃，这高于该波长范围内此前报道的任何观测结果。
