On effective ion beam charge at under inertial confinement fusion conditions

G.M. Ovezov1996年Fusion Engineering and DesignIF 1.7出版社

AbstractFor a thermally non-equilibrium system that consists of a monoenergetic ion beam propagating through a partially ionized plasma at a density up to solid state, an approximate equilibrium formula is obtained following entropy considerations that relate to ion beam charge states, including the dependence on the beam velocity and substance, and on the medium substance, temperature and density. At low temperatures, as a consequence the Bohr-Lamb criterion, an ‘average ion’ approximation is derived (in the Lamb version). Also, if the beam substances and that of the medium are the same, and the beam velocity equals zero, then Saha's formula for the ionization equilibrium is obtained.

熱的に非平衡な系、すなわち固体密度までの密度を有するプラズマ中を伝播する単一エネルギーイオンビームからなる系に対して、エントロピー考察に基づいて、イオンの電荷状態に関連する近似的平衡式が導出される。これには、ビームの速度および物質、ならびに媒質の物質、密度、温度への依存性が含まれる。低温では、その結果としてボーア・ラムの判定基準に基づき、「平均イオン」近似が(ラムの形式で)導出される。さらに、ビームの物質と媒質の物質が同一であり、ビーム速度がゼロの場合には、電離平衡に関するサハの式が得られる。
