Thermally assisted photoemission effect on CeB_{6} and LaB_{6} for application as photocathodes
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 materi...
