Description

A Continuous Wave (CW) Radio Frequency Quadrupole (RFQ) accelerator is being designed for the Rare Isotope Accelerator (RIA) Driver Linac. This device is required to accelerate a wide variety of species as well as perform simultaneous acceleration of multiple charge states. As such, the structure must operate over a wide range of RF power dissipation from {approx}0.65 kW to 48 kW. The physics design of this pseudo split-coaxial RF structure has been established by ANL in collaboration with ITEP (Moscow) and the preliminary engineering design is under way at AES. The design addresses the requirements for efficient cooling throughout the ... continued below

Description

A Continuous Wave (CW) Radio Frequency Quadrupole (RFQ) accelerator is being designed for the Rare Isotope Accelerator (RIA) Driver Linac. This device is required to accelerate a wide variety of species as well as perform simultaneous acceleration of multiple charge states. As such, the structure must operate over a wide range of RF power dissipation from {approx}0.65 kW to 48 kW. The physics design of this pseudo split-coaxial RF structure has been established by ANL in collaboration with ITEP (Moscow) and the preliminary engineering design is under way at AES. The design addresses the requirements for efficient cooling throughout the structure, precise alignment, reliable RF contacts, and fine tuning capability. The favored approach employs furnace brazing for fabrication of details and complete RFQ segments. Six longitudinal segments are mechanically assembled to form the complete 4-meter RFQ structure. Other methods of fabrication and/or assembly such as electroforming remain under consideration. This paper will discuss the engineering design and the trade studies performed to arrive at the primary configuration.
