Abstract

We examine specific features of the collimation system of a tomograph for testing steel products based on Compton backscattering. The device is described and the parameters of the primary pinhole collimator of the collimation system are calculated. The device allows reliable scanning of a steel test object by simply displacing the pinhole perpendicular to the X-ray axis from the tube anode within 50 mm with a focal length of 163 mm.

钢铁产品反照率层析成像准直系统中针孔的计算参数

摘要

我们研究了基于康普顿反向散射的层析成像仪准直系统的特定功能，以测试钢铁产品。描述了该设备，并计算了准直系统的主针孔准直器的参数。通过简单地将垂直于X射线轴的针孔从管阳极移到50 mm以内，焦距为163 mm，该设备就可以可靠地扫描钢质测试对象。
