METHOD FOR RECOVERING ION BY HEATING PHOTOIONIZED PLASMA USING ELECTROMAGNETIC WAVE

摘要

PURPOSE: To recover an isotope efficiently for a short time by irradiating a plasma with an electromagnetic wave to increase the temperature of plasma in a method for isolating a highlighted atomic isotope using an electric field. ;CONSTITUTION: A highlighted atomic isotope is isolated using an electric field by irradiating a vaporized atom (e.g. alkali metal) with an isotope with a laser beam to allow it to be photoionized into a plasma. In this case, the isotope is efficiently recovered in a short time by emitting an electromagnetic wave 4 of lower frequency than plasma frequency to a photoionized plasma 3 to increase the temperature of the plasma 3. That is, efficient recovery of the ion is achieved, if the temperature of the photoionized plasma is low and the recovery time is long.;COPYRIGHT: (C)1994,JPO&Japio
