径向场漂移室与多线比例室结合在一起，可对来自点源的 X 射线光子进行成像。位置信息是从与室阴极相关的正交 RC 线的终端信号的上升时间获得的。探测器的有用物平面为 140 mm*140 mm。在一个方向上的分辨率约为 0.4 毫米 (RMS)，但在正交方向上受到阳极线间距的限制。对均匀漂移场探测器和径向漂移场探测器的图像质量进行了比较。
A radial field drift chamber has been incorporated with a multiwire proportional chamber to image X-ray photons from a point source. Positional information is obtained from the rise time of the terminal signals from orthogonal RC lines associated with the chamber cathodes. The detector has a useful object plane of 140 mm*140 mm. Resolution is approximately 0.4 mm (RMS) in one direction but is limited in the orthogonal direction by the anode wire spacing. Comparison of picture quality is made between uniform drift field and radial drift field detectors.
