WebThe detector receives less beta particles and then sends a signal to the rollers to increase the force on the foil, making it thinner. If the foil is too thin it absorbs less beta particles.
WebA calorimeter measures the energy a particle loses as it passes through. It is usually designed to stop entirely or “absorb” most of the particles coming from a collision, forcing them to deposit all of their energy within the detector, thus measuring their full energy. Calorimeters have to perform two different tasks at the same time ...
