| Fermilab is involved in an effort to assemble 3.9 GHz
superconducting RF cavities into a four cavity
cryomodule for use at the DESY TTF/FLASH facility as a
third harmonic structure. The design gradient of the
cavities is 14 MV/m. This effort involves design,
fabrication, intermediate testing, assembly, and eventual
delivery of the cryomodule. We report on all facets of this
enterprise from design through future plans. Included will
be test results of single 9-cell cavities, lessons learned,
and current status. | |

| The International Linear Collider (ILC) will require two
dipole cavities to "crab" the electron and positron bunches
prior to their collision. It is proposed to use two 9 cell
SCRF dipole cavities operating at a frequency of 3.9 GHz,
with a transverse gradient of 3.8MV/m in order to provide
the required transverse kick. Extensive numerical
modelling of this cavity and its couplers has been
performed. Aluminium prototypes have been
manufactured and tested to measure the RF properties of
the cavity and couplers. In addition single cell niobium
prototypes have been manufactured and tested in a
vertical cryostat. | |
