Development of a future multi-TeV warm collider demands new technological solutions and new accelerator structure materials. The Ka-Band test facility being put into operation at Yale University that centers on the Yale/Omega-P 34-GHz magnicon allows users to carry out high gradient experiments on RF breakdown, pulse fatigue, tests of new high power pulse manipulation systems, and RF components. The magnicon is now conditioned for a pulse width up to 1 μs, at an output power level high enough for basic studies of electric and magnetic RF field limits at surfaces of conductors and dielectrics. The high-power waveguide transmission system for the facility is assembled and ready for tests. It includes RF windows, phase shifters, 13 mm diameter TE 11 waveguides, mode converters, etc. Recently the assembled system has undergone conditioning in preparation for carrying out first "user" experiments.
