x-ray apparatus

The X-Ray Apparatus consists of an experiment chamber contained in a closed, radiation-proof housing with a transparent synthetic glass shield.

The product has safety features in place to ensure it is both user-friendly and dependable. As well as the casing being radiation-proof, if the synthetic glass shield is opened, the high-voltage source for the X-ray tube automatically deactivates. Safety features like these are crucial in regard to potential radiation exposure.

The X-Ray Apparatus makes a great addition to any lab, allowing the user to conduct various experiments including those involving fluorescent radiation and Bragg's reflection. 

Features of the x-ray apparatus

  • High vacuum X-ray tube
  • Radiation-proof housing, synthetic glass shield - for your safety
  • High voltage source for X-ray tube automatically deactivates if shield is opened
  • Directly heated tungsten cathode and copper anode
  • 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 a swiveling arm
  • In the form of a slide tray, this arm serves as a mount for the Geiger-Müller tube, ionisation chamber and also experimental devices in slide formator on a 5 x 5cm base plate
  • The swiveling arm can be rotated manually independently of the sample holder, or at a fixed mutual angle with a ratio of 2:1 - useful in experiments involving Bragg's reflection
  • The device is equipped with angle and millimeter scales, position markings for experimental devices and radiation-proof bushings for cables and hoses
  • Also includes one cable to measure the tube current

Experiment topics

The X-Ray Apparatus can be used to support the following experiment topics:

  • Properties of X-rays: transmission, linear propagation, ionisation, X-ray photography
  • Fluorescent radiation
  • Shielding of X-rays
  • Absorption experiments
  • Distance law
  • Dosimetry and radiation protection
  • Diffraction of X-rays: Laue's recordings, Debye-Scherrer's recordings, Bragg's reflection, Duane-Hunt's displacement law (h-determination)
  • Moseley's law
