A primary object of the present invention is to increase the magnetic field along the path of a charged particle beam so as to improve TWT performance. Related objects of the invention are to achieve a higher maximum peak field along the aforementioned particle beam path, to magic sphere disclosed in the co-pending application of H. Leupold a present co-inventor, Serial No , , filed. The magic sphere is a hollow spherical flux source that produces a uniform high-field in its spherical central cavity. The hollow sphere is comprised of magnetic material and its magnetization is azimuthally symmetrical. An axial bore hole through the magnetic poles provides access to the uniform high-field in the central cavity. Patent applications. JES
