With the Electron Diffraction Tube one can verify the de Broglie hypothesis and establish the dual nature of the electron. In addition, one can calculate the interatomic spacings of carbon, (the diffracting material in the tube). (Cables are not included in the system.)
Also available is the same system but with the MCP power supply.
Recreate the first experiment to measure the charge to mass ratio of the electron. Your students can deflect the electron beam with electrostatic forces, magnetic forces, or both. This experiment helped usher in modern physics at the turn of the twentieth century, and provides the ability to calculate the speed of the electron beam by balancing electrostatic and magnetic forces.
- Deflection of electrons in a closed circular path inside a magnetic field.
- Determination of specific charge of an electron e/m.
Introduce your students to nuclear magnetic resonance spectroscopy and relaxometry. The detailed manual will allow anyone to measure T1 and T2 values for a variety of solids and liquids. Works with both 1H and 19F.
Intrinsic Angular Momentum or Spin is a basic property of nuclei and electrons. Although Spin cannot be measured directly, the magnetic dipole moment is closely related and can be observed.
- Measure NMR/ESR line width
- Determine g factor
- Study line shape
The Advanced Spectroscopy System for USB includes the Universal Computer Spectrometer with software in a 1K, 2K or 4K version, TEL-SP38 complete scintillation probe with stand, base and cable, TEL-RSS8 set of 8 radioactive sources including an "unknown", and the "Experiments in Gamma Spectroscopy" manual (on CD).
With the Basic X-Ray System students can perform over 10 x-ray detection experiments using photographic techniques and the Geiger-Muller tube. Students can investigate Laue x-ray diffraction, Bragg diffraction on single crystals, and x-ray emission. Properties of x-ray, such as rectilinear propagation, inverse square relationship, and penetration and absorption can also be shown.

You can now eliminate most of the frustrations and aggravation in performing this historic experiment with this new cutting edge technology developed and patented by Dr. Randall Peters. (Click here for a detailed explanation of these unique sensors.) The use of this simple device to measure the gravitational constant G (in a single lab period!) will impress your students in a way no textbook or even video can match.
