Fermilab
| |
| | 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. | |
