Ohgaki The thermally assisted photoemission (TAPE) effect was investigated for the hexaboride thermionic cathodes ( LaB 6 and CeB 6 ). It was found that the quantum efficiency of these cathodes can be increased by raising the cathode temperature along with the thermionic emission. In addition both materials ca... [Phys. Rev. Accel.
