These elements account for fluid heat transport and heat transfer coefficients. To determine the coolant temperature rise, one-dimensional pipe flow elements were used. The thermal model includes the cavity vanes, walls and all coolant channels. The heat loads were then transferred to a thermal model of a single segment and scaled to match total heat loss obtained from the code CST Microwave Studio. RF analysis was used to determine the heat loss distribution on the cavity surfaces. This paper more ยป discusses RF, thermal and structural analyses that have been completed in response to these requirements. Some of its principal design requirements include efficient cooling of components, mechanical stability, precise alignment and fine tuning of the resonant frequency during operation. The physics design was developed by ANL and the preliminary engineering design by AES. Therefore, the structure must operate over a wide range of RF power dissipation, from less than 1kW to about 48 kW. This device is capable of accelerating a variety of masses as well as simultaneously accelerating multiple charge states. The RFQ design for the Rare Isotope Accelerator (RIA) driver operates at 57.5 MHz, room temperature and is CW, Continuous Wave. Finally, we explored the beam's dynamics with a particle in cell (PIC) simulation, validated the results and compare them with 2D code result. = also was used to predict the field within the cavity particularly, a combination of transient/eigenmode solvers was employed to accurately construct the RF field for the particles, which also includes the effects of the couplers.
