Loading inventors, assignments & file history…
Abstract
Interposing a programmable path length of one or more materials into a particle beam modulates scattering angle and beam range in a predetermined manner to create a predetermined spread out Bragg peak at a predetermined range. Materials can be “low Z” and “high Z” materials that include fluids. A “high Z” and, independently, a “low Z” reservoir, arranged in series, can be used.
Claims (5)
1 . A charged particle beam scatterer/range modulator comprising:
a fluid reservoir having opposing walls in a particle beam path;
a drive to adjust the distance between the walls of the fluid reservoir; and
a programmable controller for the drive to adjust the distance between the walls of the reservoir during exposure of a target to the beam.
