Abstract
Abstract An X-ray television microscope has a mirror disposed in a radiation protection chamber in the path of an X-ray beam between the object being irradiated and an X-ray source and at an angle of 45* relative to the X-ray beam axis. The mirror permits observation and recording through a window in the working chamber of the actual position of the object being irradiated in two projections, while the X-ray beam axis is inclined to the horizontal at an angle of 30* to 60* to reduce the dimensions of the instrument and to facilitate its operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
132 words
An X-ray television microscope comprising an X-ray source: a protective casing accommodating said source; a shielded working chamber in which a test object being irradiated is disposed in the path of an X-ray beam, said chamber having a window; a converter for converting X-ray shadow images into video signals, said converter having a target and being disposed in said working chamber behind said test object in the path of the X-ray beam; a mirror housed inside said working chamber between said source and said test object, said mirror being tilted relative to the target of said converter and positioned to enable simultaneous observation through said window of the test object and the converter target in the direction of the X-ray beam; and a monitor electrically coupled to the output of said converter.
Claim 2
Dependent Claim

An X-ray television microscope comprising an X-ray source: a protective casing accommodating said source; a shielded working chamber in which a test object being irradiated is disposed in the path of an X-ray beam, said chamber having a window; a converter for converting X-ray shadow images into video signals, said converter having a target and being disposed in said working chamber behind said test object in the path of the X-ray beam; a mirror housed inside said working chamber between said source and said test object, said mirror being tilted relative to the target of said converter and positioned to enable simultaneous observation through said window of the test object and the converter target in the direction of the X-ray beam; and a monitor electrically coupled to the output of said converter.
Claim 3
Dependent Claim
53 words
An X-ray television microscope according to claim 1 wherein the reflecting surface of the mirror is tilted at an angle of 45* in relation to the longitudinal axis of the converter target, while the axis of the X-ray beam is inclined at an angle of 30* to 60* with respect to the horizontal.
Claim 4
Dependent Claim
29 words
An X-ray television microscope according to claim 1 wherein said mirror consists of a material exhibiting low X-ray absorption characteristics, and a visible-light reflecting film deposited on said material.
