摘要:

我们表明,散射矩阵计算的偶极模式之间的23-43 GHz的206细胞失谐结构(DS)是一致的有限元计算和非耦合模型的结果。特别是,这些频带的尾流均方根和与第一偶极子频带的尾流均方根和相当。我们还表明,对于RDDS 1非耦合尾场计算较高的频段是一致的测量。特别是,一个明确的26 GHz的信号,在短距离尾流中被发现在这两个结果。

英文摘要:

We show that scattering matrix calculations for dipole modes between 23-43 GHz for the 206 cell detuned structure (DS) are consistent with finite element calculations and results of the uncoupled model. In particular, the rms sum wake for these bands is comparable to that of the first dipole band. We also show that for RDDS1 uncoupled wakefield calculations for higher bands are consistent with measurements. In particular, a clear 26 GHz signal in the short range wake is found in both results.
