Abstract :
Summary form only given. A W-band extended interaction klystron (EIK) driven by a 19.5-kV, 3.5-A sheet beam is being developed. Simulations using the 3-D particle-in-cell codes MAGIC and ICEPIC predict saturated output power levels of 8-10 kW with a saturated gain >;30 dB and small signal gain >;40 dB. A beamstick has been successfully fabricated and tested, transporting 98% of the emitted current through a 0.4-mm × 5-mm × 20-mm-long beam tunnel. Performance of the beamstick was in excellent agreement with MICHELLE simulations.
