Description
Using a 6MeV S-band rf linac, a compact FEL system for a wide wavelength range is being developed at ILT. It covers radiation wavelengths from ∼10μm to a few millimeters. For an efficient FEL operation, we developed a high-brightness electron beam source. A photocathode driven by a Nd:YAG laser has been installed in the rf gun. We found that heated metal photocathode (LaB6, W) provided sufficient beam brightness and long lifetime. Significant improvement of the beam quality (ΔE/E∼1%, Bn∼1011 A/m2rad2) was achieved. The photocathode operation was investigated in detail by our simulation code. (author)
