A 3-MeV X-band linac has been de­vel­oped em­ploy­ing a cost-ef­fec­tive split struc­ture de­sign in order to re­place ra­dioac­tive iso­tope ir­ra­di­a­tors cur­rently used for the Ster­ile In­sect Tech­nique (SIT) and other ap­pli­ca­tions. The pen­e­tra­tion of a Co-60 ir­ra­di­a­tor can be matched with Bremsstrahlung pro­duced by a 3-MeV elec­tron beam. The use of elec­tron ac­cel­er­a­tors elim­i­nates se­cu­rity risks and haz­ards in­her­ent with ra­dioac­tive sources. We pre­sent the cur­rent state of this X-band split struc­ture linac and the rest of the ir­ra­di­a­tor sys­tem.

In this work, we sug­gest and in­ves­ti­gate new mag­net­less cir­cu­la­tors based on three res­onators con­nected in a loop and para­met­ri­cally mod­u­lated in time with mu­tual phase lag. The first de­sign con­sists of three Fano res­onators with a spec­trally asym­met­ric re­sponse, in con­trast to schemes based on the Lorentz res­onators ex­plored thus far. The sec­ond de­sign in­cludes three Fano-Lorentz res­onators, i.e., it also pos­sesses spa­tial asym­me­try. We demon­strate that the asym­met­ric ap­proach pro­vides strong and re­versible iso­la­tion for the prac­ti­cally fea­si­ble mod­u­la­tion am­pli­tude and rate. The re­sults of our work are promis­ing for pre­cise mea­sure­ments of su­per­con­duct­ing radio fre­quency cav­i­ties with high Q-fac­tor.
