摘要

Abstract

This article presents a prototype of beam position and phase measurement (BPPM) electronics designed for the LINAC in China Accelerator Driven Sub-critical system (ADS). The signals received from the Beam Position Monitor (BPM) detectors are narrow pulses with a repetition frequency of 162.5 MHz and a dynamic range more than 40 dB. Based on the high-speed high-resolution Analog-to-Digital conversion technique, the input RF signals are directly converted to In-phase and Quadrature-phase (,IQ,) streams through under-sampling, which simplifies both the analog and digital processing circuits. All signal processing is integrated in one single FPGA, in which real-time beam position, phase and current can be obtained. A series of simulations and tests have been conducted to evaluate the performance. Initial test results indicate that this prototype achieves a phase resolution better than 0.1 degree and a position resolution better than 20 μm over a 40 dB dynamic range with the bandwidth of 780 kHz, which is well beyond the application requirements.
