Development of a Small-Period, Linear, Wiggler Magnet for a Ubitron
Abstract
A double-sided wiggler magnet with period on the order of 1 cm has been optimized and improved in design. Good peak to peak uniformity along with tapered entrance conditions has been achieved. Peak magnetic field in the range 1-3 kG is easily realized so long as the gap separating the two sides of the magnet is smaller than about one half of a wiggler period. Such a restriction on gap separation implies that a ubitron utilizing a rectangular waveguide circuit could not be made to operate at its fundamental frequency with electron energy below 100 keV. Investigation of a third harmonic ubitron utilizing a linear wiggler is recommended to achieve operation at electron energy in the range 30-60 keV.
