We presen. multiphysics design.studies for thermal man.gemen. of a 325 MHz 3 MeV Radio Frequen.y Quadrupole (RFQ) structure for the fron. en. of 1 GeV proton.lin.c for proposed In.ian.Spallation.n.utron.Source (ISn.). Physics design.of RFQ for ISn. application.has been.carried out for 10% (maximum) duty factor. Durin. high power operation.of RFQ, RF-in.uced heatin. would result in.temperature rise, thermal deformation. an. frequen.y shift of RFQ from design.d values. Therefore thermal man.gemen. is on. of the importan. design.con.ideration. for RFQ developmen.. Durin. design.studies, electromagn.tic an.lysis of RFQ cavity is performed to compute RF in.uced heat fluxes on.RFQ surfaces usin. SUPERFISH an. An.YS software. Simulated results for both codes were compared an. foun. in.well agreemen.. A water coolin. scheme has been.design.d to absorb RF in.uced heat from RFQ structure. Coolin. parameters are optimized by employin. un.variate search method optimization.techn.que. An.RF-Thermal-Structural-RF coupled multi-physics an.lysis methodology is developed to evaluate thermal in.uced frequen.y detun.n. of ISn. RFQ structure. Parametric studies are carried out to in.estigate the effect of coolin. water temperatures on.RFQ frequen.y. Based on.an.lysis results, coolin. water temperatures are varied to restore RFQ frequen.y to design.d values. Thus, water coolin. will n.t on.y remove heat from structure, but it will also be used for on.in. con.rol of reson.tin. frequen.y durin. steady state operation.of RFQ structure. Results of n.merical studies carried out for thermal man.gemen. of ISn. RFQ are presen.ed in.this paper.
