AbstractTo solve the design problem of an inertial thermonuclear fusion facility requires the united efforts of scientists in various countries. In the field of heavy ion fusion a collaboration between scientists in Germany and Russia is under successful development.VNIIEF possesses advanced software for numerical simulation of the processes in thermonuclear target operation. This paper describes a target design suggested and being studied by scientists of Frankfurt University and GSI which is based on 2D non-stationary calculation of the X-ray energy transport and capsule compression. The target consists of a spherical capsule with DT fuel and an ellipsoidal chamber containment. The ion beam energy is released in two fixed converters located on the chamber axis symmetricall 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 research is to estimate the effect of gas dynamic expansion of the chamber walls, shields and capsule on the target operation. To increase the reliability of the obtained results and the assessment of probable errors in predicting radiation field parameters and the capsule state, the calculations were accomplished in a kinetic arrangement with various techniques.

要約 慣性熱核融合の設計問題を解決するには、重イオン核融合の分野において、各国の科学者たちの協力的な取り組みが必要である。ドイツとロシアの科学者たちの協力による研究は、現在、ロシア連邦核センター(VNIIEF)で成功裏に進められている。VNIIEFは、熱核ターゲットの作動過程をシミュレーションするための高度なソフトウェアを保有している。フランクフルト応用科学大学(FHU)の重イオン慣性核融合(HIIF)グループは、重イオンビーム駆動式ターゲットの設計とシミュレーションのためのコードを開発している。VNIIEFのコードとFHUのコードを組み合わせることで、重イオン駆動式ターゲットの設計とシミュレーションのための強力なツールが得られる。本稿では、そのようなターゲットの設計とシミュレーションの結果を紹介する。
