First FRIB production cryomodule complete
FRIB-1, the first fully populated cryomodule for the FRIB driver linear accelerator, is complete. This is significant because it means great strides have been made in assembly time: FRIB-1 was completed in two-and-a-half months, compared to the six months it took to complete cryomodules for ReA3 and ReA6, other state-of-the-art accelerators at the laboratory.
The FRIB-1 cryomodule contains eight superconducting radiofrequency (SRF) beta=0.085 quarter-wave resonators, three superconducting focusing solenoids and three beam-position monitors. The module will likely be the first cryomodule to be installed in the linear accelerator tunnel for commissioning in February 2017.
The cryomodule-assembly tasks completed in less than three months included magnetic shield installation, cryogenic welding and multi-layer insulation.
