Abstract

Beam Position Monitoring (BPM) systems are utilized extensively in particle accelerator facilities as a diagnostic tool to ascertain quantitative aspects of an accelerated charge-beam such as spatial position and intensity of the beam as it is accelerated to greater velocities and levels of kinetic energy within said accelerating machine. A critical aspect of a BPM system is the Radio Frequency Front End (RFFE) electronic circuitry that receives the incoming raw BPM signal and performs signal-conditioning such that its frequency spectrum is transformed from radio frequency (RF) to non-RF and digitization of the transformed signal by downstream components can successfully occur. While front-end implementations such as RF heterodyne receivers or peak-detectors are commonly used to transform the incoming signal into digitizable form, a front-end implementation is proposed and investigated in this study that utilizes a three-stage active filter consisting of a bi-junction-transistor in common-emitter configuration to amplify the incoming signal and a standard LC bandpass-filter to filter and elongate it so that digitization of it by downstream Sample And Hold (SAH) and Analog To Digital Converter (ADC) components can successfully occur.
