Items starting with X
The experiment chamber is contained in a closed, radiation-proof housing with a transparent synthetic-glass shield. The high vacuum X-Ray tube with the directly heated tungsten cathode and copper anode is positioned in a borosilicate glass chamber with a thin walled, concave ray emission window. A lead glass hood with a collimator causes X-rays to emerge in parallel with the experiment plane and provides a shield against scattered radiation. The horizontal counter tube goniometer consists of a central sample holder and the swiveling arm. In the form of a slight ray, this arms serves as a mount for the GM Tube, ionization chamber as well as experimental devices in slide format or on a 5cm X 5cm base plate. This swiveling arm can be rotated manually independently of the sample holder or at a fixed mutual angle with the ratio of 2:1, for instant, for experiments involving Bragg's refection. The devices equipped with angle and mm scale, position marking for experimental devices, as well as radiation proof bushings for cables and houses.
