Application of real-time digitization techniques in beam measurement for accelerators

Beam measurement is very important for accelerators. In this paper, modern digital beam measurement techniques based on I Q（In-phase ＆ Quadrature-phase） analysis are discussed. Based on this method and highspeed high-resolution analog-to-digital conversion, we have completed three beam measurement e...

Description
Summary:Beam measurement is very important for accelerators. In this paper, modern digital beam measurement techniques based on I Q（In-phase ＆ Quadrature-phase） analysis are discussed. Based on this method and highspeed high-resolution analog-to-digital conversion, we have completed three beam measurement electronics systems designed for the China Spallation Neutron Source（CSNS）, Shanghai Synchrotron Radiation Facility（SSRF）, and Accelerator Driven Sub-critical system（ADS）. Core techniques of hardware design and real-time system calibration are discussed, and performance test results of these three instruments are also presented.
