“…For example, in the ATLAS HL-LHC upgrade, the gigabit-ethernet link is implemented in a modular DAQ test system for CMOS pixel sensor R & D [14]. In EAST experiments, the control system needs a lot of diagnostic data, so the ethernet network is used to transfer diagnostic data to the data server in every time-slice (defined in their DAQ program) [15,16]. In a data logger for gaseous detectors, an ethernet port is interfaced with a local LCD unit for displaying all measured parameters [17].…”

Two main protocol stacks for gigabit ethernet are currently widely adopted in the data acquisition system for high energy physics experiments. The first method is based on User Datagram Protocol (UDP), which transfer packets before an agreement is provided by the receiving party. However, the second method, called Transmission Control Protocol (TCP), establishes a connection through a process of the three-way handshake. We designed two FPGA projects, based on UDP and TCP respectively, on such a real application as ethernet communication module for ALICE calorimeters. The test of both projects is carried out on the same Xilinx Virtex-6 FPGA board, and data is captured through a professional network protocol analyzer. We analyzed the implementation methods and complexity, the variation patterns of data throughput, and the resource utilization of the two designs. The findings obtained under the same application scenario and test platform not only reveals the variation rule of actual data throughput, but also proved that the TCP would require twice as much FPGA resource for implementation as the UDP.

Experimental Advanced Superconducting Tokamak (EAST) was built to demonstrate high-power, long-pulse operations under fusion-relevant conditions, with major radius R = 1.9 m, minor radius a = 0.5 m, and design pulse length up to 1000s. It has an ITER-like D-shaped cross-section with two symmetric divertors at the top and bottom, accommodating both single null and double null divertor configurations. EAST construction was started in 2000, and its first plasma was successfully obtained in 2006. In the past 15 years, plasma-facing components, plasma heating, diagnostics, and other systems have been upgraded step by step to meet its mission on exploring of the scientific and technological bases for fusion reactors and studying the physics and engineering technology issues with long pulse steady-state operation. An advanced steady-state plasma operation scenario has been developed, and plasma parameters were greatly improved. Meanwhile, front physics on the magnetic confinement plasmas have been systemically investigated and lots of fruitful results were realized, covering transport and confinement, MHD stabilities, pedestal physics, divertor and scrap-off layer (SOL) physics, and energetic particle physics. This brief review of EAST on engineering upgrading, stand-steady operation scenario development, and plasma physics investigation would be useful for the reference on construction and operation of a superconducting tokamak, such as ITER and future fusion reactor.
