摘要：
We have experimentally studied the potential distribution in hydrogen plasma and measured its density and electron temperature in the tandem involving a circular multicusp magnetic trap and a positive-to-negative ion convertor. It is confirmed that the plasma potential in the circular trap is lower than the chamber wall potential. It is established that plasma potential in the ion convertor is virtually independent of the convertor potential in the working range.
