An evacuated high transmission prism spectrograph using a microchannel plate detection system with resistive strip readout was flown behind a precision pointing telescope on a sounding rocket. The construction, preparation, flight performance, and calibration stability of the system are discussed. Despite the adverse environmental conditions associated with sounding rocket flights, the microchannel detector system performed well. Far uv spectra (1160-1750 A) of stellar and planetary objects were obtained; spectral features with fluxes as low as 0.06 photons cm(-2) sec(-1) were detectable. This was achieved by operating the plates at lower than normal gains, using sensitive pulse counting electronics with both upper and lower limit discriminators, and maintaining the spectrograph and detector at a pressure of ~10(-6) Torr until reaching altitude.
一台使用带电阻条读出的微通道板探测系统的抽空式高透射棱镜光谱仪搭载在探空火箭上的精密指向望远镜后方飞行。文中讨论了该系统的构造、准备工作、飞行性能以及校准稳定性。尽管探空火箭飞行存在不利的环境条件，但微通道探测器系统运行良好。获得了恒星和行星天体的远紫外光谱（1160 - 1750 Å）；通量低至0.06光子·厘米⁻²·秒⁻¹的光谱特征也可被检测到。这是通过以下方式实现的：以低于正常增益操作微通道板，使用带有上下限鉴别器的灵敏脉冲计数电子设备，并在到达高空之前将光谱仪和探测器保持在约10⁻⁶托的压力下。
