THE MECHANICAL ENGINEERING DESIGN OF THE FETS RFQ

This paper will present the mechanical engineering design for a 324 MHz 4-vane RFQ, which has been developed for the Front End Test Stand (FETS) project based at the Rutherford Appleton Laboratory (RAL) in the UK. The design criteria will be discussed along with particular design features of the RFQ including the tuners, vacuum ports, main body cooling pocket design and the support/alignment structure. Different techniques for creating the RF and vacuum seal between major and minor vanes are also discussed.
