翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Momentum compaction ： ウィキペディア英語版 Momentum compaction The momentum compaction or momentum compaction factor is a measure for the momentum dependence of the recirculation path length for an object that is bound in cyclic motion (closed orbit). It is used in the calculation of particle paths in circular particle accelerators (like synchrotrons), and for astronomical objects that are bound by gravitation. For a perturbed orbit, the momentium compaction factor is defined as the derivative of normalized path length difference to normalized momentum $\backslash alpha\_p\; =\; \backslash frac\; =\; \backslash frac\; \backslash frac\; =\backslash frac\; \backslash oint\; \backslash frac\backslash mathrms$. Furthermore the momentum compaction is closely connected to the so-called slip-factor $\backslash eta$ with the horizontal dispersion $D\_x$ and the gyroradius $\backslash rho$ $\backslash alpha\_p\; =\; \backslash frac\{\backslash gamma^\{2\}\}-\backslash eta$ wherein $\backslash gamma$ is the Lorentz factor. ==References== Category:Orbits 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Momentum compaction」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
