We are
building a high-power electron injector
as part of our ERL project at Cornell
University. The injector consists of a
DC photoemission gun, a buncher cavity,
a superconducting accelerating section,
many beam diagnostics, and a 500 kW beam
dump. The goal of the project is to
demonstrate that one can produce the
very low emittance beams that are needed
for an ERL, with bunch charges up to 77
pC and a maximum average current of 100
mA. The current status of all the major
components will be reviewed, along with
recent experimental results and
construction progress.
