The Flash Radio Ther­apy is a rev­o­lu­tion­ary new tech­nique in the can­cer cure: it spares healthy tis­sue from the dam­age of the ion­iz­ing ra­di­a­tion main­tain­ing the tumor con­trol as ef­fi­cient as in con­ven­tional ra­dio­ther­apy. To allow the im­ple­men­ta­tion of the FLASH Ther­apy con­cept into ac­tual clin­i­cal use, it is nec­es­sary to have a lin­ear ac­cel­er­a­tor able to de­liver the very high dose and very high dose rate (>106 Gy/s) in a very short ir­ra­di­a­tion time (beam on time < 100ms). Low en­ergy S-band Linacs (up to 7 MeV) are being used in Ra­dio­bi­ol­ogy and pre-clinic ap­pli­ca­tions but in order to treat deep tu­mors, the en­ergy of the elec­trons should achieve the range of 60-100 MeV. In this paper, we ad­dress the main is­sues in the de­sign of a com­pact C band (5.712 GHz) elec­tron linac-VHEE for FLASH Radio Ther­apy. We pre­sent pre­lim­i­nary stud­ies on C-band struc­tures at La Sapienza and at INFN-LNS, aim­ing to reach a high ac­cel­er­at­ing gra­di­ent and high cur­rent nec­es­sary to de­liver a dose >1 Gy/pulse, with very short elec­tron pulse.
