NSNS RFQ mechanical design

A 402.5 MHz, 6% duty factor RFQ is being designed for the National Spallation Neutron Source (NSNS). The 6% duty factor and RFQ length will present formidable design challenges. To this end, an RFQ materials test program is underway. A cold model test facility is being designed. Results of cooling calculations have begun. Plans for cavity construction, RF and vacuum seals, alignment, structural support and hot models are discussed.
