| | Cornell University is developing and fabricating a SRF
injector cryomodule for the acceleration of the high current
(100 mA) beam in the Cornell ERL prototype and ERL
light source. Major challenges include emittance preservation
of the low energy, ultra low emittance beam, cw cavity
operation, and strong HOM damping with efficient HOM
power extraction. Axial symmetry of HOM absorbers, together
with two symmetrically placed input couplers per
cavity, avoid transverse on-axis fields, which would cause
emittance growth. Fabrication of five 2-cell niobium cavities
and coaxial blade tuners, ten twin high power input
couplers, and six beam line HOM absorbers has finished.
The injector cryomodule is presently under assembly at
Cornell University with beam test planned for early 2008.
In this paper we report on the cryomodule fabrication and
assembly status. | |
