CARBON ION BEAM INJECTOR APPARATUS AND METHOD OF USE THEREOF

摘要

A charged particle cancer therapy system is used to accelerate an anion, such a C−, and to convert the anion to a cation, such as C6+, through use of one or more electron extraction subsystems. A first example of an electron extraction subsystem is a hydrogen gas electron stripping system. A second example of an electron extraction subsystem is a carbon foil electron stripping system. The resultant cation is accelerated in a synchrotron, transported along a beam-line, and targeted to a tumor resulting in ablation of the tumor.

1. An apparatus configured to strip electrons from charged particles, the apparatus comprising:
a tandem accelerator comprising:
a beam path;a vacuum tube circumferentially surrounding a portion of a longitudinal axis of the beam path;a first electron extraction subsystem, comprising:
a carbon stripping foil axially crossing the beam path, during use the charged particles comprising positively charged particles traversing said carbon stripping foil, said carbon stripping foil configured to strip electrons from the positively charged particles traversing through said carbon stripping foil; andmeans for forming a vacuum seal between said carbon stripping foil and said vacuum tube.
