X 射线象增强管目前已广泛应用于医疗诊断和工业探伤等领域,是十分有效的观测手段。为了对被观测部位所包含的大小不等的细节都能提供满意的图象信息,所以要发展变倍型管。用此种器件装备的 X 射线电视系统,系通过管内电子图象变倍来获得两种甚至三种不同尺寸的视野,以增加使用功能。因此,随着此类管种技术上的日趋完善,在国外的产品系列中,变倍型管已逐渐居于主要地位,我厂亦于84年开展了此项产品的研制工作。本课题的工作目标可概括为如下三点:一.考虑到下阶段研制的新管型,将采用结构衬底的碘化铯屏。根据国外产品介绍,其
X-ray intensifier tubes are widely used in medical diagnosis and industrial flaw detection and other fields and are very effective means of observation. In order to provide satisfactory image information for the varying sizes of the parts to be observed, a variogram tube has to be developed. An X-ray television system equipped with such a device is capable of obtaining two or even three different sizes of field of view by zooming the electronic image in the tube to increase the usage function. Therefore, with the gradual improvement of such tube technology, the zoom tube has gradually taken the lead in foreign product lines. The factory also started the development of this product in 1984. The objectives of this task can be summarized as the following three points: First, taking into account the new stage of the development of the new tube, the structure of the substrate will be cesium iodide screen. According to foreign product introduction, its
