Electron diffraction tube D

Electron diffraction tube D

Supplier: 3B Scientific

Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.

Tube holder S

Tube holder S

Supplier: 3B Scientific

Tube holder to support all S series electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage. The base plate has a slot for attaching the Helmholtz pair of coils S.

Electron deflection tube D

Electron deflection tube D

Supplier: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.
