  To meet the re­quire­ments of con­duct­ing high en­er­gy den­si­ty physics and plas­ma physics re­search at HIR­FL-CSR. The high­er ac­cel­er­at­ing gap volt­age was re­quired. A mag­net­ic alloy (MA)-core load­ed radio fre­quen­cy (RF) cav­i­ty which can pro­vide high­er ac­cel­er­at­ing gap volt­age has been stud­ied in In­sti­tute of Mod­ern Physics, Chi­nese Acade­my of Sci­ences (IMP, CAS), Lanzhou. To se­lect prop­er MA ma­te­ri­al to load the RF cav­i­ty, mea­sure­ment for MA cores has been con­duct­ed. The MA core with high­er shunt impedance and lower than 1 qual­i­ty fac­tor (Q value) should be se­lect­ed. The the­o­ret­i­cal cal­cu­la­tion and sim­u­la­tion for the MA-core load­ed RF cav­i­ty can be con­sis­tent with each other well. Fi­nal­ly 1000kW power was need­ed to meet 50-kV ac­cel­er­at­ing gap volt­age by cal­cu­la­tion.
