The tritium balance based on pressure measurements in the divertor was performed for the DTE1 campaign carried out at JET in 1997. This is a complementary analysis to the integrated tritium inventory already reported for a full day of experiments. The particle balance shows that the T flux retention is about 1.26 x 10(21) T s(-1) during a plasma pulse (similar to 65% of the injected flux). Outgasing between pulses reduces this T inventory to about 30% of the injected fluence. This detailed gas balance also shows that the retention of hydrogen species depends on the plasma isotopic ratio. However, during the D clean-up pulses, the amount of T removed by isotopic exchange is shown to be limited to about 2 x 1023 T. Finally, the total particle balance (D + T) is shown to be independent of the plasma isotopic ratio. (c) 2004 Elsevier B.V. All rights reserved. |
