The RF-cavity, running in long pulse/ CW mode, will deliver 9 MeV energy gain to the charged beam at the exit by taking its advantage of multiple accelerations with the same field at a frequency of 10⁷.5MHz. A substantial amount of power loss will be dissipated on the RF surface of the cavity within beam time. Further electromagnetic (EM) optimization was performed on a standard coaxial model with slight modifications aiming to achieve a higher shunt impedance, thus less power loss on surfaces. A proper water cooling design is still required to prevent large scale temperature rise on the cavity wall. The corresponding effects on cavity mechanical stability and resonant frequency shifting are concerned. This paper will present the details in the EM, thermal, structural analysis of the RF-cavity.
