VGB8194

CPI gyrotron amplifiers are the only commercially available W-band amplifiers with high peak and average output powers. The VGB-8194, a five-cavity amplifier, can be operated at peak output powers up to 100 kW and average output powers up to 10 kW. The full-width-half-maximum bandwidth is 700 MHz and the saturated gain is 35 dB. A CVD diamond window, developed for use on high-power gyrotron oscillators, has been adapted for the amplifier. The VGB-8194 is available with a refrigerator-cooled 4 Telsa superconducting magnet which does not require liquid cryogens. diamond window collector 4T Superconducting Magnet 53.1 inches (1.35 meters) circuit electron gun Typical Operating Parameters Features • • • • • • High Power Broad Bandwidth High Gain Axial Output CVD Diamond Output Window Cryogen-Free Superconducting Magnet Peak Output Power 100 kW Avg.
