Abstract

Abstract

The longitudinal and lateral straggling was analyzed in the irradiation of hot electrons into DD and DT fusion plasma. The result shows that the longitudinal and lateral straggling linearly increases with increasing the penetration range which is in some relation to plasma mass. The calculated error mainly results from the lateral straggling, with the value below 5%, or millions of amperes. When the electron energy is fully deposited in the hot spot, the focusing angle is 20.64 for DD plasma and 21.8 for DT plasma in the edge-ignition mode, and is 16.36 for DD plasma and 17.6 for DT plasma in the center-ignition mode. The condition for the electronic beam focusing angle is easily achieved.
