我们利用带有 CCD 相机的光学成像气体探测器,成功检测到了 /sup 109/Cd 和 /sup 241/Am 的 22 keV 和 30 keV X 射线的光电子轨迹图像。大多数 30 keV 光电子在氙气中的径迹长度大于 1 毫米。轨道的图像包含像素簇,并且对每个轨道的这些簇中最亮的像素进行了详细研究。研究发现这些团簇的几何中心与最大能量损失点不同。
We have successfully detected images of tracks of photoelectrons from the 22 keV and 30 keV X rays of /sup 109/Cd and /sup 241/Am, utilizing an optical imaging gas detector with a CCD camera. Most of the 30 keV photoelectrons have track lengths greater than 1 mm in xenon gas. The images of the tracks contain clusters of pixels, and the brightest of these clusters, for each track, were investigated in detail. It was found that the geometric center of these clusters differed from the point of maximum energy loss.
