Measure how X-ray photons lose energy as they scatter, and confirm the Compton formula directly.


Photons of the molybdenum K α X-ray line are scattered at the quasi-free electrons of an acrylic glass cuboid. The energy of the scattered photons is determined in an angle-dependent manner with the aid of a swivelling semiconductor detector and a multi-channel analyser.
All units adapted for 110V/60Hz. Contact us for volume pricing and grant assistance.
Swing the detector around the scatterer. The larger the angle, the more energy each X-ray photon hands to an electron.
Bring this to your lab →Photons of the molybdenum Kα line strike an acrylic glass scatterer.
A swiveling semiconductor detector and multichannel analyzer record the scattered photon energy.
Compare the measured energy shift with the Compton equation and determine the Compton wavelength.
Scattered photon energy falls as the angle increases, following the Compton equation (illustrative).
Yes. Units supplied through American Scientific are adapted for 110V/60Hz and supported in the U.S., including warranty and replacement parts.
Tell us about your lab in the form above and we'll put together a complete, ready-to-teach configuration, so nothing is missing on day one.
Often, yes. Many institutions fund PHYWE equipment through NSF, Title IV and CTE programs, and our team can help you find and apply for the right opportunity.
