In the development of high-power free-electron lasers, intense electron beams are required. Large area, directly heated lanthanum hexaboride cathodes have been proposed as the electron emitter. To aid in the design of the cathode, the resistivity of lanthanum hexaboride as a function of material density and temperature has been measured.

    Lanthanum hexaboride (LaB6) is investigated for its potential as a low work-function photocathode for high brightness e-beam applications. Thin films of LaB6 at room temperature are shown to have quantum efficiencies of 0.2×10-3 at 442 nm excitation but readily form an inhibiting oxide. This...
