Abstract :
A field emission electron gun with a carbon-nanotube (CNT) cathode has been installed in the KEKB/PF linac, and the beams extracted from the gun have been accelerated to the end of the linac to 2.5 GeV. We confirmed that the beams can easily stand comparison with the usually injected beams, which are extracted from a thermionic gun installed nearby.
