A microwave scanning ESR microscope has been developed to study the distribution of paramagnetic ions or radicals in various materials, especially in minerals. The microwave scanning microscope consists of a cavity with an aperture over which a sample is moved using mechanical stages and computer-controlled stepping motors. The EPR signal intensities at all positions are composed on a CRT display as an image. A new TE111-mode cylindrical cavity system was designed to obtain better sensitivity and resolution. ESR images of gamma-rayed human teeth were obtained to study the effect of secondary electrons from the adjacent metal on the defect formation in a tooth.
已开发出一种微波扫描电子自旋共振显微镜，用于研究各种材料，尤其是矿物中顺磁性离子或自由基的分布。该微波扫描显微镜由一个带有小孔的腔体组成，样品通过机械平台和计算机控制的步进电机在小孔上方移动。所有位置的电子顺磁共振信号强度在阴极射线管显示器上合成一幅图像。设计了一种新的TE111模式圆柱腔系统，以获得更好的灵敏度和分辨率。获取了经伽马射线照射的人类牙齿的电子自旋共振图像，以研究来自相邻金属的二次电子对牙齿中缺陷形成的影响。
