Conception design of helium ion FFAG accelerator with induction accelerating cavity

HEATHER – HElium ion Accelerator for radioTHERapy∗

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 ...

Preliminary Design of a Perpendicular Biased Ferrite Loaded Accelerating Cavity

A ferrite loaded accelerating cavity with a frequency sweep of 18 to 40MHz is studied for a possible upgrade of the CERN accelerator complex. The resonance frequency of a ferrite loaded cavity shifts by applying an external magnetic bias field to the ferrite material by means of changing the relative permeability. We present the electromagnetic design of such a cavity with a special emphasis on...

The Light Ion Pulsed Power Induction Accelerator for Etf*

The light ion Engineering Test Facility (ETF) driver concept, based on Hermes III and RHEPP 2 technologies, is a scaled-down version of the LMF design incorporating repetition rate capabilities of up to 10Hz. The preconceptual design presented here provides 250-TW peak power to the ETF target during 8 ns, equal to 2-MJ total ion beam energy. Linear inductive voltage addition driving a self-magn...
