Abstract

The laser irradiated GaAs-cathode with NEA surface can produce an electron beam with spin polarization and other attractive performances. Present status of best performances, such as polarization, quantum efficiency, current density, brightness, energy resolution, and continuous operation time etc. are explained using our experimental data. Finally, a recent work to enable the real-time observation of the magnetic domain formation process using a new polarized electron source is reported.
