Development of a thomson scattering diagnostic System on EAST

Plasma Science and Technology 2010年第2期12卷 144-148页

作者：臧庆赵君煜杨利胡庆生贾燕庆张涛席晓琦 S.H.BHATTI 高翔 Institute of Plasma Physics Chinese Academy of Sciences

A multipulse and multipoint Nd：YAG （neodymium-yttrium aluminum garnet） laser thomson scattering diagnostic system was developed on EAST to obtain more accurate electron temperature Te and electron density ne profiles. In this paper, the optical system, the VME （versa module eurocard）-based real-time computer system for laser control, data acquisition, analysis and calibration are discussed in detail. Furthermore, a developed data processing method is presented.

Plasma Science and Technology 2010年第3期12卷 284-288页

作者：杨利万宝年赵君煜胡庆生贾燕庆席晓琦韩效锋臧庆 Institute of Plasma Physics Chinese Academy of Sciences

Primary physical design of the thomson scattering system for EAST, including the configuration of the system and the design considerations of different sections of the system, is presented. The expected measurability of this design, namely an electron temperature of 513 eV to 5 keV and a plasma density beyond 0.5× 10^19 m^-3, fulfills the requirements of the EAST operation.

Design and development of a synchronized operation control system for thomson scattering diagnostic on J-TEXT

Plasma Science and Technology 2018年第8期20卷 1-5页

A thomson scattering diagnostic system is under construction at the Joint Texas Experimental Tokamak（J-TEXT）. A 1064 nm Nd：YAG laser with 50 Hz repetition rate is used as the laser source. We have used a software for careful and precise control of the laser through serial communication. A time sequence operating system has been developed to synchronize the laser control and data acquisition system with the central control system（CSS）. The system operates commands from the CSS of J-TEXT and generates triggers for the laser and data acquisition system in the proper sequence. It also measures an asynchronous time value that is needed for accurate time stamping. All functions are served by a field-programmable gate array development platform that is suitable for high-speed data and signal processing *** embedded peripherals, including Ethernet and USB 2.0, provide communication with the CSS and the server.
