Description

Lanthanum hexaboride has been tested as a photoemitter when irradiated by a KrF eximer laser. Measured current, from 0.4cm2 emitting area, was 10 A at irradiating wavelength of 248 nm; current density was about 25 A/cm2. Beam normalized rms emittance measured with pepper pot method was 20 mm-mrad. The corresponding normalized rms brightness was about 2.5 x 1010 A/m2-rad2. The quantum efficiency was about 1.0 x 10-4. The chamber pressure was better than 2 x 10-6 torr. Further research is underway
