质子加速器

Proton generated from a Cockroft-Walton accelerator in the energy range of 30-100 keV were appropriately collimated and made to pass through a 10 g/cm^2 carbon foil. After Rutherford scattering, proton uniformly irradiated TLDs which were placed at the 20° behind and 20 cm away from the carbon foil. We used a channeltron behind TLD holder as the proton detector.
