A Prototype of an ATCA-Based System for Readout Electronics in Particle and Nuclear Physics
Thousands of channels and large amount of data in the modern high-energy and nuclear physics pose many challenges for readout electronics, so that system of high bandwidth, low latency and flexible real time data sharing is very necessary. Because of the limit of the architecture, the classical parallel backplane cannot meet the requirement. A prototype readout electronics system based on Advanced Telecom Computing Architecture (ATCA) is designed, which is composed of a hub blade and node blades. The blades interconnect with each other via high speed serial links of ATCA backplane. A high sample rate Analog to Digital Converter (ADC), which can readout the signal from the detectors, is implemented to produce high speed data for transmission, and a Filed Programming Gate Array (FPGA) is responsible for configuration, control and data transmission. The system tests conducted in the laboratory indicate that the prototype system functioned well.
