A Fixed Field Alternating Gradient Accelerator for Helium Therapy
نویسندگان
چکیده
A non-scaling fixed field alternating gradient (nsFFAG) accelerator is being designed for helium ion therapy. This facility will consist of 2 nested rings, treating with helium ions (He) and image with hydrogen ions (H + 2 ). Compared to protons, ions deliver a more conformal dose with a significant reduction in range straggling and beam broadening. Carbon ions are currently used and there are no current facilities providing helium therapy. We are investigating the feasibility of an FFAG approach for helium therapy, which has never been previously considered. We investigate emittance and demonstrate that the machine meets isochronicity requirements for fixed frequency RF.

A non-scaling fixed field alternating gradient (nsFFAG) accelerator is being designed for helium ion therapy. This facility will consist of 2 superconducting rings, treating with helium ions (He2+) and image with hydrogen ions (H + 2 ). Currently only carbon ions are used to treat cancer, yet there is an increasing interest in the use of lighter ions for therapy. Lighter ions have reduced dose ...
متن کاملA New Type of Accelerator for Charged Particle Cancer Therapy
Non-scaling Fixed Field Alternating Gradient accelerators (ns-FFAGs) show great potential for the acceleration of protons and light ions for the treatment of certain cancers. They have unique features as they combine techniques from the existing types of accelerators, cyclotrons and synchrotrons, and hence look to have advantages over both for this application. However, these unique features me...
متن کاملOptimizing Non-scaling Ffag Lattices for Rapid Acceleration
An approach to fixed field acceleration using exclusively linear optical elements was first proposed[1, 2] and successfully developed[3, 4] to support rapid, large-emittance muon acceleration required by a Neutrino Factory or Muon Collider. This approach was termed, simply, a non-scaling, fixed field alternating gradient (FFAG) accelerator. Lattices have evolved from the simple F0D0-cell baseli...

PAMELA (Particle Accelerator for MEdicaL Applications) is a design study of a novel accelerator for cancer therapy using protons and carbon ions. The accelerator utilizes the nonscaling Fixed Field Alternating Gradient (FFAG) principle and features superconducting combined-function magnets with dipole, quadrupole, sextupole and octupole field components for steering the ion beam. The proton rin...
متن کاملID : 1088 ! Fixed Field Alternating Gradient Accelerators ( FFAG ) for Fast Hadron Cancer Therapy
Cancer accelerator therapy continues to be ever more prevalent with new facilities being constructed at a rapid rate. Some of these facilities are synchrotrons, but many are cyclotrons and, of these, a number are FFAG cyclotrons. The therapy method of “spot scanning” requires many pulses per second (typically 200 Hz), which can be accomplished with a cyclotron (in contrast with a synchrotron). ...
