Elektronrör

The quality of the electron beam in electron defraction tube S (1013889) is affected by the resistance between sockets C5 (cathode) and F4 (heating filament) on the tube. For optimum results, the resistance needs to be 390 kΩ. Tube holder S (1014525) is accordingly designed such that this resistance is present. Older designs feature a […]

An experiment model for demonstrating the Debye-Scherrer technique used in electron diffraction tubes by means of visible light. This model consists of a ball-bearing aluminum disc with a cross-lattice which rotates to simulate a poly-crystalline lattice. Includes a pinhole aperture with red and green color filters. Specifications: Cross lattice: with 20 grid points/mm, 3 mm […]

Experiment Topics: Deflection of electrons in a closed circular path inside a magnetic field. Determination of specific charge of an electron e/m. For examining the deflection of electron beams in a uniform magnetic field using a pair of Helmholtz coils (1000906) and for the quantitative determination of the specific charge of the electron e/m. Glass […]

For observing phenomena (for example cathode glow, positive column, canal rays) that occur during electrical discharge in a variety of gases at various pressures. Either end of the discharge tube is equipped with a fluorescent screen, and can be unmounted and installed in tube holder U18505. Product includes a needle ventilation valve and vacuum hoses. […]

  Elektronrör monterat på ett terminalfundament för undersökning av designen på och driften av moderna katodstrålerör. Elektronstrålen kan avledas med ett elektriskt fält som produceras av avledningsplattorna, vilka integrerats inuti röret och av ett magnetiskt fält från tre externa spolar som monterats på en ring. En Wehnelt-cylinder används för att fokusera strålen. En gasfyllning och […]
