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 with …
