CPI gyrotrons were the first commercially available high-power, long-pulse/CW, high-frequency devices for plasma fusion experiments and other scientific and industrial applications. CPI-MPP provides an extensive line of gyrotrons that cover frequencies from 28-140 GHz with power levels ranging from 10 kW to 1.3 MW. The VGT-8141 gyrotron delivers continuous wave (CW) output power levels up to 900 kW at a frequency of 140 GHz for electron cyclotron heating and current drive in fusion plasmas. 90.1 inches (2.29 meters) For additional information on gyrotrons, other CPI products, or a copy of our catalog-on-disk, please contact: CPI Microwave Power Products, 811 Hansen Way, Palo Alto, CA 94303-0750 Telephone: 650-846-3172, Fax: 650-856-0705, Email: [email protected] Page 1 of 2 Rev: 2007-03-26 Output Power vs. Beam Voltage Power & Efficiency vs. Beam Current Output Power vs. Magnetic Field Features Typical Operating Parameters • High Power, Continuous Operation • Gaussian Output Beam • CVD Diamond Output Window • Diode Electron Gun • Single-Stage Depressed Collector Power Output Pulse Length Cathode Voltage Body Voltage Beam Current Frequency Efficiency Output Mode 900 kW CW -60 kV 20 kV 40 A 140±0.3 GHz 35% TEM00 For additional information on gyrotrons, other CPI products, or a copy of our catalog-on-disk, please contact: CPI Microwave Power Products, 811 Hansen Way, Palo Alto, CA 94303-0750 Telephone: 650-846-3172, Fax: 650-856-0705, Email: [email protected] Page 2 of 2 Rev: 2007-03-26
