	A prototype 81.25 MHz dual-beam drift tube linac (DB-DTL) is being designed to proof the feasibility of multi-beam type linac. The beam dynamics design and electromagnetic calculation have been completed [1]. The following step is the multi-physics analysis of the DB-DTL. The three-dimensional multi-physics analysis is very important for the design of the DB-DTL. The RF dissipated power will make the cavity temperature rise and cause cavity resonance frequency shifting due to the deformation of cavity structure. The distributions of cavity deformation and stress are calculated according to the cavity temperature distribution. All the simulation results, including cavity temperature rise, deformation and stress and the frequency shifting resulted in cavity deformation, should be within an acceptable range. The designing goal is to design the DB-DTL operated in pulse model with 1/1000 duty factor. The detailed three-dimensional multi-physics analysis of the prototype DB-TL will be presented in this paper.

	A compact proton linac injector is being studied, HSC (Hybrid single cavity), for cancer therapy. The HSC consists of RFQ section and DTL section. Both sections are interdigital-H (IH) mode linac. The HSC with an operation frequency of 100 MHz accelerate C⁶⁺ beams from 20keV/u up to 4 MeV/u. The total length of HSC is less than 4 meters. For this purpose, we use the RFGen to design RFQ section, and PIMLOC is provided for DTL section and whole HSC.

The beam dynamics design and electromagnetic calculation have been completed [1]. The following step is the multi-physics analysis of the DB-DTL. The three-dimensional multi-physics analysis is very important for the design of the DB-DTL. The RF dissipated power will make the cavity temperature rise and cause cavity resonance frequency shifting due to the deformation of cavity structure. The distributions of cavity deformation and stress are calculated according to the cavity temperature distribution. All the simulation results, including cavity temperature rise, deformation and stress and the frequency shifting resulted in cavity deformation, should be within an acceptable range.
