Fabrication and Tolerance Issues and their Influence on Multi-Bunch BBU and Emittance Dilution in the Construction of X-Band RDDS Linacs for the NLC
- SLAC
The main linacs of the Next Linear Collider (NLC) will contain several thousand X-band RDDS (Rounded Damped Detuned Structures). The transverse wakefield in the structures is reduced by detuning the modal frequencies such that they destructively interfere and by four damping manifolds per structure which provide weak damping. Errors in the fabrication of the individual cells and in the alignment of the cells will reduce the cancellation of the modes. Here, the authors calculate the tolerances on random errors in the synchronous frequencies of the cells and the cell-to-cell alignment.
