High Energy Devices’ products are used to protect electrical equipment from destructive voltage transients or for transferring stored electrical energy, usually from a storage capacitor, to a load circuit. Our gaps are made from the highest quality materials to handle high operating voltage and current applications. These products are used extensively in some of the most demanding military environments and are typically used for protecting thyratron or hard tube modulator components, high-wattage power supply components, high voltage medical equipment, and video display tubes. These devices are also used as active switches for high voltage energy transfer or triggering applications such as flashlamps, exploding bridgewire systems (EBW), and capacitor bank discharging.

High Energy Devices’ Power Gaps consist of two metal electrodes hermetically sealed in a gas filled rugged ceramic cylinder. The coaxial electrode system of these devices is designed to handle high energy pulses. The Power Gap is used to protect signal and power lines from transients generated by sources such as lightning and other electro-magnetic impulses. Applications are found in avionics, military, industrial and medical equipment. PMT/UMT(275)

High Energy Devices' Uni-Imp Series provides the ultimate in surge protection from high energy, fast rising transients. These devices are constructed using a proprietary semiconductor junction process which results in nanosecond response times combined with peak current ratings in the 5,000-10,000 ampere range. A unique benefit of this technology is that the breakdown voltage is virtually independent of the rise time of the transient. In addition, the low capacitance of these devices allows direct placement on high frequency lines and antenna feeds without excessive loading. Applications are found in military, industrial and medical equipment.
High Energy Devices’ Spark Gaps are designed for a wide variety of applications requiring the efficient transfer of high voltage, high energy pulses. Typical applications include overvoltage protection of magnetrons, diodes, capacitors, and other components in high voltage circuits and as switching devices in pulse generating circuits. High Energy Devices’ miniature spark gaps have been designed for applications that have severe environment and high reliability requirements and where cost is a major consideration. BX Series
High Energy Devices’ Triggered Spark Gaps, which have main static breakdowns up to 60kVdc, are high energy spark gaps which are capable of switching stored energy in a fraction of a microsecond upon command. Triggered Spark Gaps require no standby power, are extremely rugged and require only a low energy, high voltage pulse. Applications include crowbars, exploding bridge wire systems, and xenon flashlamp triggers. High Energy Devices’ miniature Triggered Spark Gaps, which have main static breakdowns between 2.0 and 10.0kVdc, have been designed for applications where cost is a major consideration, but high reliability switching is still required.

High Energy Devices’ gas discharge source is the element in a microwave RF system that makes possible accurate measurements of the noise figure of the receiver or its components. The requirements of a device used for making such noise figure measurements include broad bandwidth inherent in the active element, stability, ease of operation and long life. When the gas discharge noise tube is mounted and terminated normally, it presents a “white signal” of constant intensity over a bandwidth limited only by the system or mount. In general, the range of usefulness of these noise sources permits measurements of noise figures from about 2 to 30db. Existing mountings provide a useful frequency range of approximately 100MHz to 100GHz.
