Abstract

Rapid, quantative assessment of x-radiation source intensity distributions would be useful in several areas of radiation physics. A simple x-ray sensitive CCD based camera for the measurement of focal spot and radiation beam intensity profiles has been constructed. Focal spot images recorded with the CCD camera and radiographic emulsion are compared and the advantage of the CCD camera in rapidly recording true radiation intensity distributions is demonstrated.

摘要

对X射线源强度分布进行快速定量评估在辐射物理学的多个领域都将是有用的。我们构建了一种基于简单的X射线敏感电荷耦合器件（CCD）的相机，用于测量焦点和辐射束强度分布。将用CCD相机记录的焦点图像与射线照相乳胶记录的图像进行比较，证明了CCD相机在快速记录真实辐射强度分布方面的优势。
