Helical resonator ion accelerator and neutron beam device

摘要

A Helical Resonator Ion Accelerator in which ions are injected into a hollow dielectric pipe forming a vacuum chamber along which the ions are accelerated. The pipe is wrapped with a coil and positioned inside a metal pipe. The dielectric pipe, the coil and the metal pipe are arranged coaxially on an axis along which ions are accelerated. The metal pipe is positioned within a high intensity 0.5-3.0 Tesla solenoid. A pulse generator is coupled to the coil to generate a voltage wave pulse. The pulse travels down the axis of the accelerator on the helix formed by the coil. An ion source injects deuteron ions along the axis of the vacuum chamber. A traveling voltage wave is accelerated by tapering the characteristic velocity of the accelerator in the direction of wave propagation by tapering the coil and the outer metal pipe together in a constant ratio.
