1 d calculations on transport, neutral injection heating and ignition control in ZEPHYR
Description
1 - d transport calculations and particle trajectory calculations for neutral injection in Zephyr show that without impurity radiation losses a heating power of 20 MW and a pulse length of 1 s should be sufficient to reach ignition in Zephyr (average densities in the compressed stage between 2 and 4.5 x 1014 cm-3). The injection system should have an acceleration voltage of 160 keV; lower energy neutrals require higher heating powers. Heating of the plasma in the compressed stage requires neutral particle energies of > approx. 250 keV. Active burn control of the nearly ignited plasma is possible with heating powers of about 1 MW and response times of the feedback system smaller than 200 ms. (orig.) 891 HT/orig. 892 HIS
