Abstract :
Electron emission current from LiTaO3 excited by Nd:YLF laser light and X-ray from a counter electrode were measured. X-ray was observed to keep the constant intensity by shortening a time interval between irradiation. Dependence of the electron emission pattern and the spot size on the distance between the crystal and the screen was measured. The electron beam was found to be focused at a distance of 5 mm.
