Method and apparatus for interaction with a modulated off-axis electron beam |
September 13, 2011 |
| An output circuit for a microwave tube is provided that has generally high interaction impedance for good efficiency, has high average power capability, and is physically large for a given operating frequency. The output circuit is designed to operate in conjunction with an off-axis, |

Bowtie deflector cavity for a linear beam device |
August 24, 2010 |
| A resonant cavity with a bowtie shape supports an electromagnetic field used to deflect the trajectory of an electron beam passing through the cavity. The short transit time of the beam across the gap maintains the cavity fields at near-optimal phase, improving interaction efficiency |

Method and apparatus for RF input coupling for inductive output tubes and other emission gated d |
March 30, 2010 |
| An input circuit of a microwave amplification tube achieves improved instantaneous bandwidth. By directly coupling the transmission line carrying a modulating radio frequency signal to a control grid, a low-Q input circuit is created that increases the fractional bandwidth of the sys |

Compact scanned electron-beam x-ray source |
December 29, 2009 |
| A compact, reliable scanning electron-beam x-ray source achieves reduced complexity and cost. In particular, the x-ray source includes an electron beam that is propagated parallel to an x-ray target and is swept across the target in response to a moving magnetic cross field. Rather than |

Apparatus and method for trajectory modulation of an electron beam |
December 29, 2009 |
| An electron beam amplification device provides trajectory modulation of an electron beam, and includes an electron gun, a modulator, an interceptor, an output circuit, and a collector. The electron gun produces an electron beam. The modulator receives an RF input signal and provides a |
