The High Efficiency International Klystron Activity (HEIKA) collaboration seeks to improve the efficiency of CW klystrons, with an eye to their use as RF sources for future particle accelerators.  Through investigating novel bunching techniques, such as the core oscillation method (COM), and bunching-alignment-collection (BAC) method, klystrons with predicted efficiencies approaching 90% have been demonstrated across numerical codes including AJDISK, MAGIC2-D, KlypWin, TESLA and Klys2D.  Recent numerical results of such devices featuring solid, cylindrical electron beams, will be presented.
