TI - Thermo-Mechanical Calculations for the SPES RFQ J2 - Proc. of Heavy Ion Accelerator Technology Conference (HIAT2015), Yokohama, Japan, 7-11 September 2015 AB - Within the SPES project at INFN-LNL a new injection line will be built at INFN LNL in order to transport and match the RIBs to the existing ALPI superconducting linac. This line includes a new RFQ that will operate in a CW mode (100% duty factor) at the operating frequency of 80MHz. The RFQ is composed of 6 modules about 1.2 m long each. Each module is in turn basically composed of a Stainless Steel Tank (AISI LN 304) and four OFE Copper Electrodes. A copper layer will be electrodeposited on the tank inner surface and a spring joint between tank and electrode is used in order to seal the RF. Moreover, the electrodes are equipped with two brazed SS inserts in order to allow coupling with the tank. In order to remove the RF power (about 100 kW) as well as to allow frequency control during high power operation for a given cooling channel layout, a set of thermo-structural simulations was performed, whose input data were the RF Power densities calculated with 2D and 3D codes. In this paper the analytical and numerical methods used, as well as the main outcomes of these studies are presented.
