Title: Leonard Knowles Brundle: Innovator in Linear Accelerator Technology

Introduction

Leonard Knowles Brundle is a notable inventor based in Haywards Heath, GB. He has made significant contributions to the field of linear accelerator technology, holding a total of four patents. His work has implications in various applications, particularly in medical imaging.

Latest Patents

Brundle's latest patents include innovative designs for linear accelerators. One of his patents describes an accelerator that comprises a plurality of accelerating cells arranged to convey a beam. Adjacent cells are linked by a coupling cell, which dictates the ratio of the electric field in the respective adjacent accelerating cells. This design allows for a switchable coupling cell that can alternate between a positive and a negative ratio. By imposing a negative ratio, the beam encounters a reversed electric field in subsequent cells, effectively decelerating it. This technology enables the development and bunching of the beam in early cells while accelerating to relativistic energies, and then reducing the beam energy to levels comparable to diagnostic X-rays.

Another patent details a standing wave linear accelerator featuring multiple resonant cavities along a particle beam axis. These cavities are electromagnetically coupled via a coupling cavity, which contains a rotationally asymmetric element. This element rotates about an axis parallel to the coupling cavity's axis, allowing for a simple mechanical control of the coupling value with minimal impact on the phase shift across the device.
