Photonis continues to manufacture a wide range of special purpose power tubes for research applications. Our tetrodes, triodes and cavities are integral parts of linear accelerator power sources in laboratories throughout the world. We manufacture our power tubes of research and special applications to custom specifications to ensure your research is accurate and reliable. Photonis offers pulsed RF amplifiers that include a wide selection of tubes, matching cavities and integral cavity modular amplifiers for pulsed RF service at frequencies up to 1400 MHz. These tubes feature anode, grid and drive pulsed ratings, pulse lengths to 2200 µsec, duty cycles to 25% and peak power to 8 megawatts. Phase stability and broadband capability makes these tubes ideal for applications ranging from linear-accelerator drives to fire-control radar.
Our Series Regulators & Hard Tube Modulators feature sturdy, fault-resistant cathodes and clean, high voltage designs which make these types ideal for modulation and control of pulsed RF amplifiers, klystrons, TWTs and more in modern shaped-pulse and pulse width-controlled systems. Our tubes can support pulse currents up to 90 amperes along with hold-off voltages up to 200kV. Photonis also offers distributed amplifiers that are high gain, ceramic/metal tetrodes with dual input configuration. These tubes are specifically designed for distributed amplifier services up to 500 MHz. High gain, ceramic/metal tetrodes with matching cavities are available for use as pulsed RF sources in accelerator services.
