CERN超低能反质子(ELENA)环是一种新的同步加速器，将于2016年投入使用，以进一步减速从CERN的反质子减速器(AD)转移的反质子。由于旋转频率的摆动以及所需的数字信号处理，对纵向诊断信号的采集和处理的要求非常苛刻。对低电平射频(LLRF)系统的要求也非常高，特别是在进行腔体电压控制和数字信号处理所需的旋转频率摆幅、动态范围和低噪声方面。这两组要求都将通过使用尖端硬件系列来满足，该系列硬件旨在满足Meyrin站点所有同步加速器的LLRF需求；它将于2014年首次部署在欧洲核子研究中心的PSB和医疗机器Medauthon中。本文概述了硬件系列的主要构建块以及相关的固件和IP核。
The CERN Extra Low ENergy Antiproton (ELENA) Ring is a new synchrotron that will be commissioned in 2016 to further decelerate the antiprotons transferred from the CERN’s Antiproton Decelerator (AD). The requirements for the acquisition and treatment of signals for longitudinal diagnostics are very demanding, owing to the revolution frequency swing as well as to the digital signal processing required. The requirements for the Low-Level Radio-Frequency (LLRF) system are very demanding as well, especially in terms of revolution frequency swing, dynamic range and low noise required by the cavity voltage control and digital signal processing to be performed. Both sets of requirements will be satisfied by using a leading-edge hardware family, developed to cover the LLRF needs of all synchrotrons in the Meyrin site; it will be first deployed in 2014 in the CERN’s PSB and in the medical machine MedAustron. This paper gives an overview of the main building blocks of the hardware family and of the associated firmware and IP cores.
