Abstract

Abstract:

An extensible high-speed accelerator data acquisition system (ADAS) for the Dragon-I linear induction accelerator has been developed. It comprises a VXI crate, a
controller, four data acquisition plug-ins, and a host computer. A digital compensation algorithm is used to compensate for the distortion of high-speed signals arising from longdistance transmission. Compared with the traditional oscilloscope wall, ADAS has significant improvements in system integration, automation, and reliability. It achieves unified management of data acquisition and waveform monitoring and performs excellently with a 107-ps high-accuracy trigger and 32-channel signal monitoring. In this paper, we focus on the system architecture and hardware design of the ADAS, realization of the trigger, and digital compensation algorithm.
