Similar to the Backward Wave Oscillator (BWO), the PASOTRON spontaneously generates microwave radiation by efficiently converting electron beam energy into electromagnetic radiation. The PASOTRON, however, utilizes a novel E-gun and plasma-filled slow-wave structure (SWS) to produce and propagate very long, high-power beam pulses which require no axial magnetic fields for transport. The long electron beam pulses are obtained from a Hughes Hollow-Cathode Plasma (HCP) E-gun, which employs a low-pressure glow discharge to provide a stable, high current-density electron source. Electrons from this source are accelerated through a multi-aperture array to produce a large area, high-current beam consisting initially of many individual beamlets. Since the device is operated in the ion focused regime, the plasma filling the SWS, space-charge neutralizes the beam, and the Bennett self-pinch compresses the beamlets and increases the beam's current density. Experimental results from a PASOTRON tube designed to operate in a TM01 mode at C-band frequencies when driven by a 50-to-100-kV, 50-to-250 A electron beam are reported. Results show output power is in the l-to-4 MW range, for rf pulselengths up to 100 μsec, corresponding to an integrated energy per pulse of up to 300 J. Calculations show the E-beam to microwave-radiation power-conversion efficiency is ~20%. Instantaneous bandwidth measurements further reveal that for the duration of the long ripulse the PASOTRONs oscillation center frequency maintains a narrow line <;3MHz.","PeriodicalId":241775,"journal":{"name":"1992 9th International Conference on High-Power Particle Beams","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126664477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CLIA system consists of (from the load back to the mains) a ten-cell linear induction voltage adder, ten magnetically switched water insulated pulse forming lines (PFL's), a two-stage Magnetic Compression Unit (MCU), and thyratron-switched Intermediate Energy Store (IES), and Command Resonant Charge (CRC) units. This system was conceived to drive repetitive e-beam loads for various types of repetitive testing. A linear induction accelerator system was used because it allows all pulse compression to be done at moderate voltage (40 to 150 kV) and then uses the accelerator structure to add parallel voltage pulses into a single high voltage output (750 kV). Nowhere except at the load does a voltage of higher than 150 kV appear. This allows the switching to be done at moderate voltage and the use of hydrogen thyratrons and magnetic switches is possible. This generator has been in operation at Physics International for over a year and has achieved all its design goals. The design and operational characteristics of the accelerator will be described in this paper.","PeriodicalId":241775,"journal":{"name":"1992 9th International Conference on High-Power Particle Beams","volume":"52 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
