Software Radio for Beam Excitation
Triggered signal generation for transverse excitation of stored particle beams as required for tune diagnostics and RF Knock Out resonant slow extraction. This repository contains the software, firmware and documentation to turn a Software Defined Radio (SDR) such as the Ettus USRP X310 into a ready-to-use beam excitation system. Implemented using GNU Radio and RFNoC.
