摘要:

横向四维梁均方根参数的知识对于涉及耦合两个横向自由度(平面)的晶格单元的应用是必不可少的。特别感兴趣的是去除平面间的相关性,以减少投影发射度。一个专用的发射度测量旋转系统(ROSE)已被提出,开发,并成功地委托,以充分确定四维光束矩阵。该装置已被用于在GSI的高电荷注入器(HLI)使用的束线,这是由一个斜四极三重态,一个正常的四极偶极子,和ROSE。本文报道了1.4MeV/u ~(83)Kr 13+离子束的数学算法、测量和结果。

英文摘要:

Knowledge of the transverse four-dimensional beam rms-parameters is essential for applications that involve lattice elements that couple the two transverse degrees of freedom (planes). Of special interest is the removal of inter-plane correlations to reduce the projected emittances. A dedicated ROtating System for Emittance measurements (ROSE) has been proposed, developed, and successfully commissioned to fully determine the four-dimensional beam matrix. This device has been used at the High Charge injector (HLI) at GSI using a beam line which is composed of a skew quadrupole triplet, a normal quadrupole doublet, and ROSE. Mathematical algorithms, measurements, and results for ion beams of 83Kr13+ at 1.4 MeV/u are reported in this paper.
