Bragg peak - Wikipedia
https://en.wikipedia.org/wiki/Bragg_peak
WEBThe Bragg peak is a pronounced peak on the Bragg curve which plots the energy loss of ionizing radiation during its travel through matter. For protons, α-rays, and other ion rays, the peak occurs immediately before the particles come to rest. It is named after William Henry Bragg, who discovered it in 1903.

WEBBragg Peak. The Bragg peak, as we use the term, is the on-axis depth-dose distribution, in water, of a broad quasi-monoenergetic proton beam. A carefully measured Bragg peak is essential to accurate range modulator design. Listing the most important factor first, the shape of the Bragg peak depends on the fundamental variation of stopping power ...

WEBMar 24, 2015 · Pristine Bragg peak: The pristine Bragg peak is simply the maximum (or mode) dose near the end of range, and is located at z BP, which is defined next. The physical processes governing the location and/or height of the peak are mainly the proton stopping power and energy straggling, nuclear reactions to a much lesser extent and, for …
