Abstract :
The principal parts of accelerators are electron sources, which operate in some cases in field electron emission mode and can be developed as multi-tip field emission arrays (FEAs). Using an FEA with thermally smoothed tips, field emission current of 20.5 A was obtained in the pulse mode. The highest field emission current obtained using a non-thermally smoothed FEA was 175 A in the pulse mode.
