AB - Wire scanners are a main diagnostic tool for transverse beam size and emittance measurements at LCLS. The original SLAC wire scanners were not optimized for speed (taking minutes to scan), and can't perform at the desired level of position resolution necessary for measuring LCLS' small beam size. A new fast wire scanner, based on a dc linear servo motor, has been designed and installed in the LCLS. The new fast wire scanner has several advantages over the original wire scanner: scan times are reduced from minutes to seconds while minimizing wire vibrations. Rather than counting open-loop step pulses, the new fast wire scanner uses real time position capture for beam synchronous sampling of the wire position, enhancing beam profile accuracy.
