Abstract :
Results are presented of measurements of both longitudinal and transverse wakefields performed at the Argonne National Laboratory Advanced Accelerator Test Facility with two SLAC-built X-band disk-loaded waveguides: a conventional 30-cavity long constant-impedance structure and a nonconventional 50-cavity long structure along which the iris and spacer diameters have been varied so as to stagger-tune the HEM/sub 11/ mode frequency by 37%. The results are shown to be in excellent agreement with computations made by KN7C, TRANSVRS, TBCI, and LINACBBU.<>
