Diversified's Marx Modulator Installed at Japanese Accelerator
Marx modulator installed at Japan's KEK accelerator.
Bedford, MA — Diversified Technologies, Inc., (DTI) developer of PowerMod high voltage, high power pulse modulators, DC power supplies, and process control systems, has recently installed a 120kV, 120A, 1.7ms Marx modulator for the High Energy Accelerator Research Organization (KEK) in Japan. This is the first high power solid-state Marx bank ever commissioned.

DTI originally developed the Marx Modulator under a U.S. Dept. of Energy SBIR grant to support SLAC. The Marx bank modulator demonstrates a new technology for compact and economic ILC-class performance. Permitted by using DTI's solid-state switches instead of traditional spark gaps or SCRs, it charges an array of capacitors in parallel at low voltage and then erects them in series to form a high-voltage discharge.

According to the company, this solid-state configuration allows the capacitors to serve as storage capacitors rather than fully exhausting during each pulse and the switches also provide arc protection of the load without requiring crowbar protection. The ILC-class Marx is envisioned as a key element of the next large multi-national accelerator.
