Cal­abazas Creek Re­search, Inc. (CCR) and its col­lab­o­ra­tors are de­vel­op­ing high ef­fi­ciency, low cost RF sources. Phase and Am­pli­tude Con­trolled Mag­netrons: CCR, Fer­mi­lab, and Com­mu­ni­ca­tions & Power In­dus­tries, LLC (CPI) re­cently de­vel­oped a 100 kW, 1.3 GHz mag­netron sys­tem with am­pli­tude and phase con­trol. The sys­tem op­er­ated at more than 80% ef­fi­ciency and demon­strated rapid con­trol of am­pli­tude and phase. Mul­ti­ple Beam Tri­odes: CCR, in col­lab­o­ra­tion with CPI and JP Ac­cel­er­a­tor Works, Inc., is de­vel­op­ing 200 kW, pulsed and CW RF sources from 350 to 700 MHz with pro­jected ef­fi­cien­cies ex­ceed­ing 80% and cost of $0.50/Watt. Pro­to­type tubes are sched­uled for tests in spring 2021. High Ef­fi­ciency Kly­strons:CCR, CPI, and Lei­dos, Inc. are build­ing a 1.3 GHz, 100 kW kly­stron op­er­at­ing at 80% ef­fi­ciency. High power test­ing is sched­uled for sum­mer 2021. Mul­ti­ple Beam IOTs: CCR and Geor­gia Tech Re­search In­sti­tute are de­vel­op­ing MBIOTs with sim­pli­fied input cou­pling and high ef­fi­ciency. Sim­u­la­tions in­di­cate that 3rd har­monic drive power can in­crease the ef­fi­ciency 8-10 %. The pro­gram is de­vel­op­ing a pro­to­type tube to pro­duce 200 kW peak, 100 kW av­er­age power at 704 MHz.
