 Ives–Stilwell experiment

The Ives-Stilwell experiment is an important experiment in the field of relativistic physics that investigates the effects of time dilation, a key concept of Einstein's theory of special relativity. First conducted in the 1930s by American physicists Herbert Ives and Gilbert Stilwell, the experiment focuses on the Doppler effect of light emitted from a moving source. In the experiment, hydrogen ions (H+) are accelerated to high velocities.
