Abstract

Time-resolved mass spectrometric measurements of the H/D ratio in the neutral gas during TFR discharges were made. An analysis procedure, based on a zero-dimensional model, has been applied to the data, giving in principle the time evolution of the ion densities, of the particle confinement time, and the wall inventories. Evidence is presented for (1) a rise of the n-H/n-D ratio during the discharge, in the case of H to D isotope exchange experiments, and (2) increased wall desorption and recycling during the ion cyclotron range of frequency plasma heating. Uncertainties in the procedure are discussed.
