I.R. and F.I.R. laser polarimetry as a diagnostic tool in high-β and tokamak plasmas

AbstractAbstract

[en] The product value of the electron plasma density and poloidal B field using the polarization change (Faraday rotation) effect of a electromagnetic radiation propagating in a tokamak plasma has been done elsewhere. We propose a optical configuration in such a way to measure these product values independently and simultaneously without the use of an auxiliary interferometry set up. For our case the measurements can be done for both, high-β, theta-pinch type plasma and the Tokamak type low-β plasma. The F.I.R. laser with lambda > 1 mm is used for low-β and the I.R. laser (lambda approx. 10.6 μm) for the high-β case. (Author)

Calcula-se o valor do produto da densidade de um eletron de plasma e campo poloidal B usando-se o efeito de mudanca de polarizacao (rotacao de Faraday) de uma propagacao de radiacao eletromagnetica em plasma de tokamak. Propoe-se uma configuracao otica de maneira a medir estes valores do produto independentemente e simultaneamente sem o uso de um interferometro auxiliar. As medidas foram feitas para alto-β, plasma tipo theta-pinch e Tokamak tipo plasma de baixo β. O laser de infravermelho longinquo com lambda > 1 mm e usado para baixo-β e o laser de infravermelho (lambda aprox. 10.6 μm) para casos de alto-β. (E.G.)
