Multipulse Nd:YAG Laser Thomson Scattering Diagnostics on HT-7 Tokamak

摘要

A multipulse Nd:YAG (Neodym-yttrium aluminium garnet) laser Thomson scatter-ing diagnostic system developed was recently applied on HT-7 tokamak to obtain more accurateelectron temperatures.A CAMAC-based real-time computer system for laser control,data ac-quisition,analysis and calibration was investigated in detail.Furthermore,the reliability andaccuracy of this diagnostic system were demonstrated by comparing the results with those of asoft-X ray diagnostic system.
