Method and Device for Measuring the Location of a Particle Beam Present in Packets in a Linear Accelerator

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a method and a device for precisely measuring the position of a particle beam, delivered in discrete packets, within a linear accelerator. It does so by capturing the electromagnetic signals generated as the particle beam interacts with special sensors located inside the accelerator cavity. The method uniquely analyzes these signals at harmonic frequencies (integer multiples of the base frequency used for particle acceleration), distinctly separating the actual beam signal from background electromagnetic noise. This approach enables accurate beam position detection even within compact accelerators where traditional sensor placement is difficult.

Patent Abstract

The invention relates to a method and device for measuring the location of a particle beam (10) present in packets in a linear accelerator comprising a hollow chamber structure (4) in which an electromagnetic wave oscillating at a base frequency (f0) is generated in order to accelerate the particles, wherein an electrical measurement signal (M) generated by the particle beam (10) by means of electromagnetic interaction with the measurement recorder (16) is recorded by at least one measurement recorder (16) disposed in the hollow chamber structure (4), said signal being a function of the distance between the measurement recorder (16) and the particle beam (10). According to the invention, the measurement signal (M) is analyzed in a frequency range different from the base frequency (f0) and higher natural frequencies of the hollow chamber structure (4), comprising a whole multiple of the base frequency (f0).
