Generating high-frequency, rotating magnetic fields with low harmonic content [PDF]
Physical Review Special Topics - Accelerators and Beams, 2011 The future electron-ion collider (eRHIC) at Brookhaven National Laboratory demands a high-current, polarized, bunched electron beam [http://www.bnl.gov/cad/eRhic]. One of the challenges here is to combine the bunched beams generated by multiple cathodes so to address the issue of designing and prototyping a combiner with high-frequency (700 kHz ...
