用TraFiC4数值计算相干同步辐射效应

Numerical Calculation of Coherent Synchrotron Radiation Effects Using TraFiC4

A. Kabel, M. Dohlus, T. Limberg

摘要:

相干同步辐射(CSR)发生在短束团在强烈弯曲的轨道上行进时。它对高质量光束的影响可能是严重的,并且在定性上得到了很好的理解。然而,对于定量结果,人们必须依赖于数值方法。存在利用不同方法的若干模拟代码。我们详细描述了代码TraFiC4在DESY开发的设计和分析的目的,从第一原理的问题,并解决运动方程的扰动或自洽。给出了计算结果并与实验数据进行了比较。此外,我们给出的例子,如何代码可以用来设计光束线,由于CSR的发射度增长最小。

英文摘要:

Coherent synchrotron radiation (CSR) occurs when short bunches travel on strongly bent trajectories. Its effects on high-quality beams can be severe and are well understood qualitatively. For quantitative results, however, one has to rely on numerical methods. There exist several simulation codes utilizing different approaches. We describe in some detail the code TraFiC4 developed at DESY for design and analysis purposes, which approaches the problem from first principles and solves the equations of motion either perturbatively or self-consistently. We present some calculational results and comparison with experimental data. Also, we give examples of how the code can be used to design beamlines with minimal emittance growth due to CSR.
