Analysis of the separation of gadolinium isotopes by the ICR method

摘要

The problem of separating gadolinium isotopes is discussed. The parameters of isotope separation in a plasma by the ICR method are estimated for a device with given operating parameters. The mean transverse energy < E-perpendicular to > of the heated ions of the Gd-157 isotope and the heating efficiency eta are calculated as functions of the frequency of the RF electric field in the plasma. The dependence of the heating efficiency eta on the longitudinal temperature of the plasma flow is investigated. The issue of how the concentration of the target isotope ions at the collector plate depends on the longitudinal coordinate measured from the front edge of the plate is analyzed for different values of the frequency detuning parameter. The extraction coefficient Gamma for the target isotope is calculated as a function of the distance b between the collector plates for different frequency detunings.
