论文摘要
成功确定了一个专门确定四维光束矩阵的装置，称为Rose（用于发射量测量的旋转系统）。在物理中报道了用83kR13+在1.4 MeV/U时获得的结果。 ACCEL牧师。梁19，072802（2016）。耦合矩的精度约为10％，这足以可靠地确定可以使光束解矛的晶格。但是，相应特征发射的剩余不确定性仍然很高。本文报告了改进评估程序的报道，该程序将测得的特征发射量的不准确降低到百分比。该方法基于对其内在测量分辨率中直接测量的数据进行修剪，以便以高精度确定最终产生的数量。
A dedicated device to fully determine the four-dimensional beam matrix, called ROSE (ROtating System for Emittance measurements) was successfully commissioned. Results obtained with 83Kr13+ at 1.4 MeV/u are reported in Phys. Rev. Accel. Beams 19, 072802 (2016). Coupled moments were determined with an accuracy of about 10%, which is sufficiently low to reliably determine a lattice which could decouple the beam. However, the remaining uncertainty on the corresponding eigen emittances was still considerable high. The present paper reports on improvement of the evaluation procedure which lowers the inaccuracy of measured eigen emittances significantly to the percent level. The method is based on trimming directly measured data within their intrinsic measurement resolution such that the finally resulting quantity is determined with high precision.
