Determination of electron temperature from the emissivity ratio in the UMIST quadrupole GOLUX

A S Alhasi, J A Elliott1992年Plasma Physics and Controlled FusionIF 2.2出版社

The electron temperature of the inhomogeneous plasma of the UMIST linear quadrupole ('GOLUX') is determined by measuring the emissivity ratio of the Hbeta and Hgamma lines of the hydrogen plasma. The emissivity ratio is obtained by Abel inversion of the measured intensity of the lines. It is assumed that the free electrons have a Maxwellian velocity distribution, and that the distribution of electron population over the bound levels is given by a coronal-type equation. The hydrogen plasma is assumed to be in a steady state and without impurities contributing to the electron density.

UMIST線形四重極(「GOLUX」)の不均一プラズマの電子温度は、水素プラズマのHβ線とHγ線の放射率比を測定することによって決定される。放射率比は、これらの輝線の測定強度のアーベル変換によって得られる。自由電子はマクスウェル速度分布を持つと仮定され、束縛準位上の電子分布はコロナ型方程式によって与えられると仮定される。水素プラズマは定常状態にあり、電子密度に寄与する不純物は存在しないと仮定される。
