Query: Coaxial Wire Measurements In NLC Accelerating Structures   The coaxial wire method provides an experimental way of measuring wake fields
without the need for a particle beam. A special setup has been designed and is
in the process of being fabricated at SLAC to measure the loss factors and
synchronous frequencies of dipole modes in both traveling and standing wave
structures for the Next Linear Collider (NLC). The method is described and
predictions based on electromagnetic field simulations are discussed
