Fast atom beam scattering on a probing ion beam as a method for high-temperature plasma potential measurement

Analysis of a possibility of measuring high-temperature plasma potential distribution using the method of fast atom scattering on the probing ion beam is conducted. The method proposed is based on determining the ion beam energy depending on plasma potential from scattered atom energy spectrum. Application of the given method allows one to exclude a number of principle difficulties typical of plasma potential measurement using probing heavy ion beams. 34 refs
