X-Ray Device by 3B Scientific

The experiment chamber resides within a sealed, radiation-resistant enclosure featuring a transparent synthetic-glass shield. Upon opening the shield, the high-voltage source for the X-ray tube automatically deactivates. The high-vacuum X-ray tube, equipped with a directly heated tungsten cathode and copper anode, is housed in a borosilicate glass chamber with a thin-walled, concave ray emission window. A lead-glass hood with a collimator ensures X-rays emerge parallel to the experiment plane and shields against scattered radiation. The horizontal counter-tube goniometer comprises a central sample holder and a swiveling arm, which serves as a mount for various experimental devices. The arm can be rotated manually, either independently of the sample holder or at a fixed mutual angle of 2:1, ideal for Bragg's reflection experiments. The device is fitted with angle and millimeter scales, position markings for experimental devices, and radiation-resistant cable and hose bushings.
