APPLICATIONS

High Energy Physics

DTI's high power modulators and power supplies are used world wide in demanding research applications in the U.S. Department of Energy's national laboratories, leading universities, and overseas research facilities.

 

PowerMod™ systems are employed in RF power systems for accelerators and fusion systems, and in power conditioning and test of high power microwave tubes, such as klystrons and gyrotrons, where careful control of voltage, pulse width, and PRF, at very high power (20 MW +) and voltage (100 kV +) is required. In addition, fast-switching DTI systems can replace typical mercury ignitron crowbars by intercepting arcs before damage is done to the VED. The high voltage can be turned back on as soon as the arc clears, with nearly imperceptible interruption.
