Abstract
Under development at Argonne National Laboratory is a high-repetition-rate multi user X-ray free-electron laser (FEL) user facility. The machine will be driven by an array of highly efficient compact collinear wakefield accelerators (CWA) where the Čerenkov radiation of a 1 GeV high charge drive bunch is used to accelerate a low charge witness bunch to 5 GeV to produce X-rays in the FEL. The CWA design is based on a cylindrical corrugated waveguide with a 2 mm internal diameter embedded into a focusing channel of quadrupole magnets with a 3 mm aperture. This paper will present the metrology techniques utilized in the evaluation of various fabrication methods for producing miniature corrugated Cu waveguide structures, as well as the results obtained using a structured light 3D optical profilometer.
