Dependence on axial magnetic field of radiation from a high-power gas-filled backward wave oscillator

Abstract: Microwave output power from a high-power heliumfilled backward wave oscillator (BWO) operating at X band is measured as a function of the strength of guiding magnetic field and helium gas pressure. Tenuous helium gas filling the slow wave structure is ionized by an injected electron beam with typical parameters of energy 100 keV and current 0.5 kA. The enhancement of output power from the present gas-filled BWO is less than those reported in some previous publications. Near = 0.8 T, we observe the minimum valu… Show more

“…The relativistic backward wave oscillator (RBWO) is one of the most promising high power microwave (HPM) generators, because of its high operating stability, high output power, and excellent repetitive operation performance [1][2][3][4][5][6][7][8][9][10]. In the HPM community, researchers commonly concentrate on obtaining output with a higher power, higher efficiency, and longer pulse duration [5,[11][12][13][14][15][16][17][18][19][20].…”
