摘要：

This article describes the conventional Thomson scattering diagnostic that has been developed for multipoint measurements of the electron temperature and plasma density of the tokamak ISTTOK plasma. The design is based on a single laser pulse, two multi-input three channel spectrometers, one digital oscilloscope, and a time-delay technique. Special collection optics, optimized detectors, and high transmission monofibers with large numerical aperture have been used to increase the sensitivity and spatial resolution. The number of measurement points can be extended by increasing the number of fibers without altering the collection optics or light relay system. Results are in good agreement with those determined with other diagnostics. (C) 1999 American Institute of Physics. [S0034-6748(99)64301-5].
