  Dipole wakefields in NLC (Next Linear Collider) structures have been measured
with ASSET [1] and well predicted by a circuit model [2]. However, the
experimental technique is both time-consuming and expensive. Here, we report on
kick factor and synchronous frequency determination for 1st and higher order
dipole bands for TW (Traveling Wave) accelerators via a wire measurement
technique. This stand-alone technique is relatively inexpensive and may lead to
an efficient determination of wakefield parameters. The perturbative effect of
the wire on the dipole band is pointed out and a two-wire scheme with a limited
perturbative effect is also discussed.
