Abstract
The electron density in the plasma of toroidal screw pinch device TPE-1 of the Electrotechnical Laboratory has been measured with a conventional optical interferometer of He-Ne gas laser, 6,328 A in wavelength. The minimum phase shift detectable is about 1/300 lambda, equivalent to ..integral..nsub(e)dl=1x10/sup 15/cm/sup -2/. Some problems on this measuring system are presented. As the system uses conventional components, it is easy to construct and handle and is useful for determining plasma parameters in confinement experiments. The confinement time of charged particles is measured. As a result it has been found that the particles escape from the plasma mostly in conformity with the classical diffusion.
