For machined parts, setup time is a major component of the total time required to manufacture a machined part from a stock. If the number of setups and hence setup time can be reduced, this will not only decrease the manufacturing time, but will also ensure better machining accuracy, require fewer work-holding devices and increase machine usage time. To achieve any improvement in setup time, rs...

~-RF power is usually transmitted into ,an accelerator section from a rectangular waveguide through a single coupling iris. This arrangement introduces phase and amplitude asymmetries into the coupler fields with which the beam interacts. Field distortion can be reduced by machining an offset into the cavity wall opposite the iris. However, the compensation is imperfect. In this paper we descri...
