NUMERICAL-SIMULATION OF PERFORMANCE OF HEAVY-ION INERTIAL CONFINEMENTFUSION TARGET WITH ELLIPSOIDAL CHAMBER

To solve the design problem of an inertial thermonuclear fusion facili ty requires the united efforts of scientists in various countries. In the field of heavy ion fusion a collaboration between scientists in Ge rmany and Russia is under successful development. VNIIEF possesses adv anced software for numerical simulation of the processes in thermonucl ear target operation. This paper describes a target design suggested a nd being studied by scientists of Frankfurt University and GSI which i s based on 2D non-stationary calculation of the X-ray energy transport and capsule compression. The target consists of a spherical capsule w ith DT fuel and an ellipsoidal chamber containment. The ion beam energ y is released in two fixed converters located on the chamber axis symm etricall with respect to the capsule. The X-ray field is formed on the capsule surface with a set of special shields. The basic aim of our r esearch is to estimate the effect of gas dynamic expansion of the cham ber walls, shields and capsule on the target operation. To increase th e reliability of the obtained results and the assessment of probable e rrors in predicting radiation field parameters and the capsule state, the calculations were accomplished in a kinetic arrangement with vario us techniques.
