X Ray Apparatus (115 V 50/60 Hz)

Product Overview

Product Information:?.. The experiment chamber is contained in a closed radiation proof housing with a transparent synthetic glass shield. If the synthetic glass shield is opened the high voltage source for the X ray tube is deactivated automatically. The high vacuum X ray tube with a directly heated tungsten cathode and copper anode is positioned in a borosilicate glass chamber with a thinwalled 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 a swiveling arm. In the form of a slide tray this arm serves as a mount for the Geiger M?ller tube (U19201) ionization chamber (U19208) as well as experimental devices in slide format or on a 5 cm x 5 cm base plate (for example from U19205 U19206 U19207). The swiveling arm can be rotated manually independently of the sample holder or at a fixed mutual angle with a ratio of 2:1 for instance for experiments involving Bragg?s reflection. The device is equipped with angle and millimeter scales position markings for experimental devices as well as radiation proof bushings for cables and hoses. Specifications:?..
