The model plane scattering problem in the strip region with a sharp ledge is considered. The problem is governed by the Helmholtz equation, the Neumann condition on the boundary and the radiation condition at infinity. The method of discrete sources (MDS) along with singular value decomposition technique is used. The original ideas for the way of source allocation for sharp-pointed domains are suggested. An algorithm, permitting us to find the optimal source placement, is presented. Numerical experiments illustrate our investigations.

“…Because the NLCTA [1] is an existing facility, many constraints had to be accommodated as discussed at PAC05 [2]. While E163 needs low emittance, 50 pC bunches, the NLC is interested in bunches with charges up to 1 nC.…”

The NLC Test Accelerator (NLCTA) was built to address beam dynamics issues for the Next Linear Collider and beyond. An S-Band RF gun, diagnostics and low energy spectrometer (LES) at 6 MeV together with a large-angle extraction line at 60 MeV have now been built and commissioned for the laser acceleration experiment, E163. Following a four quad matching section after the NLCTA chicane, the extraction section is followed by another matching section, final focus and buncher. The laser-electron interaction point (IP) is followed by a broad range, high resolving power spectrometer (HES) for electron bunch analysis. Optical symmetries in the design of the 25.5 • extraction line provide 1:1 phase space transfer without sextupoles for a large, 6D phase space volume and range of input conditions. Spot sizes down to a few microns at the IP (HES object) allow testing microscale structures with high resolving power at the HES image. Tolerances, tuning sensitivities, diagnostics and the latest commissioning results are discussed and compared to design expectations.

“…For this reason, the NLC Test Accelerator (NLCTA) project [1] provides for an R & D program to develop the low-power testing techniques. These characterizing techniques are aimed at supporting different development phases of the accelerator sections; from the design, through manufacturing, and finally testing of the complete accelerator section.…”

Microwave Cold-Testing Techniques for the NLC

The R & D program for the Next Linear Collider Test Accelerator (NLCTA) includes the development of microwave techniques for testing Xband accelerating structures at different stages of design, manufacturing and assembly. During the design phase, short stacks were built and tested to finalize dimensions. Cell by cell measurements were performed on the NLCTA injector cells as a microwave quality control (QC) after manufacturing. The two injector sections were tuned using a moveable plunger and tested using a semiautomated system of bead-pull. Using this perturbation technique, we were able to map the amplitude and phase of the electric field on the axis throughout the assembled structures under traveling-wave conditions.
