Raman calibration of the HT-7 yttrium aluminum garnet Thomson scattering for electron density measurements

Qing Zang et al. Rev Sci Instrum. 2007 Nov.

Abstract

A multipulse neodym doped yttrium aluminum garnet laser Thomson scattering system calibrated by the anti-Stokes rotational Raman scattering from nitrogen gas had been developed in the HT-7 superconducting Tokmak. By virtue of this system, measured electron density results of the plasma were obtained. The results showed good repeatability and its total uncertainty was estimated to be +/-18%.
