Abstract

A new interferometric method for measuring the length of the X-ray train is proposed, and a special interferometer, a device for measurement of the X-ray train length has been developed, created, and tested. The length of the X-ray train and the duration of coherent radiation are estimated and it has been proven that the interference pattern disappears when the difference of paths between the superimposing waves becomes greater than the length of the coherent X-ray train. The bound of a disappearance of the X-ray interference pattern is determined depending on the magnitude of the path differences. The length of the X-ray train is determined, which is close to the theoretically determined value.
