摘      要：A compact room-temperature inter-digital H-mode(IH)drift tube linac(DTL)with Kombinierte Null Grad Struktur beam dynamics is proposed in this *** proposed IH-DTL,which operates at 325 MHz,accelerates 18 mA proton particles from 3.0 to 7.0 MeV as part of a proton synchrotron-based therapy *** is composed of two main sections,namely a bunching section(-30°)and accelerating section(0°).There is no transverse focusing element inside the cavity,which increases the acceleration gradient and reduces the cavity length and power *** our physical designs,LORASR code is utilized for beam dynamics design and multi-particle *** synchronous particle energy,injection phase,and acceleration voltage of each gap are optimized carefully to increase transmission efficiency while minimizing beam emittance growth and beam *** total length of the cavity is 0.82 m and the acceleration gradient reaches 4.88 MV/m,resulting in a transmission efficiency of 100%and beam emittance growth less than10%.The details of the specific work undertaken in this study are presented in this paper.
