摘要：
Field-emission arrays are Potentially a compact and bright electron source. Unlike a laser photocathode, external laser systems are not required. It is possible to have spatial control of the cathode emission. Temporal modulation up to 10 GHz may be possible. We estimate the emittance and brightness based on a reasonable FEA design. Since the FEAs are at an early stage of development for accelerator applications, many technical problems need to be addressed before they can become useful cathodes.
