Overview
GYCOM (Joint-Stock Society "Scientific & Production Enterprise 'GYCOM'") is a Russian high-technology company established in 1992 by specialists working in plasma physics and the development and manufacture of super-power vacuum microwave devices. Its central office is in Nizhny Novgorod, with branches in Moscow (GYCOM-M) and Nizhny Novgorod (GYCOM-NN). The company's core business is scientific research, development, manufacture, and sales of high-power and super-power microwave devices operating in the millimeter wavelength band — mainly gyrodevices such as gyrotrons — together with quasi-optical transmission line elements, measurement instruments, special power supplies, superconducting solenoids, and individual components of vacuum microwave devices. GYCOM's products are described as unique high-technology items based on proprietary developments, characterized by high quality and reliability. They are delivered to customers in Russia, Europe, North America, Japan, India, and China. The staff includes highly qualified experts with extensive experience in radio physics, electronics, and special engineering research, among them 8 Doctors of Science and 37 Candidates of Science in Physics & Mathematics and Engineering. The company maintains up-to-date manufacturing, engineering, and testing facilities. A major focus of GYCOM's work is gyrotrons for controlled thermonuclear fusion (UTS), including continuous-wave gyrotrons, technological installations based on medium-power continuous gyrotrons, high-power millimeter-wave amplifiers, electromagnets and superconducting magnets, microwave transmission lines and components, low-power microwave devices, frequency meters and spectrum analyzers, gyrotron output windows and barrier windows for fusion and technological installations, sub-terahertz and terahertz gyrotrons, and cathodes. The company operates two test stands for gyrotron complexes: Stand No. 1 is designed for testing prototypes and delivery samples manufactured within the ITER project, while Stand No. 2 is universal and can be flexibly configured for testing various gyrotrons. Both stands are located in adjacent rooms of one building and can be connected to common high-voltage power supplies and utilities. GYCOM positions itself as a specialized supplier of high-technology microwave and fusion-related equipment, serving research institutes and industrial customers worldwide. Its experimental base and testing capabilities support the final stage of production, where specified output parameters are verified and demonstrated to customers.
History
GYCOM was established in 1992 as a Joint-Stock Society by Russian experts working in the fields of plasma physics and the development and manufacture of super-power vacuum microwave devices. The company was founded to pursue scientific research, development, manufacture, and sales of high-power and super-power microwave devices operating in the millimeter wavelength band, primarily gyrodevices. From its base in Nizhny Novgorod, GYCOM grew to operate a Central Office and two branches: GYCOM-M in Moscow and GYCOM-NN in Nizhny Novgorod. Over the years, GYCOM developed proprietary technologies for gyrotrons, quasi-optical transmission lines, measurement instruments, special power supplies, superconducting solenoids, and vacuum microwave device components. Its products have been delivered to customers in Russia, Europe, North America, Japan, India, and China. A significant part of GYCOM's recent work has been associated with the ITER project, for which it manufactures gyrotron complexes and tests prototypes and delivery samples at its dedicated Stand No. 1. The company also operates a universal Stand No. 2 for testing various gyrotrons. GYCOM continues to be active in the development of sub-terahertz and terahertz gyrotrons and related components.
