Observing single electron pulses provides insight into the mechanism that leads to sudden high current jumps (breakdown) in aged wire chambers. This single electron activity is found to be consistent with the Fowler-Nordheim equation for field emission of electrons from a cathode surface in a high electric field. The high electric field arises from the positive ion buildup on a very thin insula...

The direct measurement of the plasma potential poses a major challenge to plasma diagnostic, and the sole tools for localized measurement of this parameter are certain forms of electric probes. For many decades emissive probes have been used in laboratory plasmas for a direct determination of the plasma potential Φpl. Only during the last years emissive probes have been applied for the first ti...

Traditional thermal sterilization technology is easy to implement and safe, but it will destroy food nutrition change taste. Therefore, people began turn their attention non-thermal sterilization. High-voltage pulsed electric field one of them; has attracted much because its high efficiency little damage food. Different types loads cause serious trailing the pulse falling edge. In view this sit...

The high-power generation capability of pulsed mode Silicon Double Drift Region (DDR) IMPATT devices has been studied by using generalized simulation software developed by the authors. The software is based on drift-diffusion modeling scheme, incorporating thermal design. After optimization of the device design, it is observed that a maximum efficiency of 9% with an output power of 15W can be a...

The goal of the LAGUNA experimental series of the Los Alamos National Laboratory TRAILMASTER program is to accelerate an annular aluminum plasma z-pinch to greater than one hundred kilojoules of implosion kinetic energy. To accomplish this, an electrical pulse )5.5 MA must be delivered to a 20 nH load in ~1 ~s. The pulsed power system for these experiments consists of a capacitor bank for initi...

The target system for a muon collider/neutrino factory requires the conjunction of an intense proton beam, a highZ liquid target and a high-field solenoid magnet. We describe the design parameters for a pulsed solenoid, including the magnet cryogenic system and power supply, that can generate transient fields of greater than 10T with a flattops on the order of 1 second. It is envisioned to loca...

Technology demonstrations of key components at LANL for the Dual-Axis Radiographic Hydro Test (DARHT) Facility including the turnkey Induction Cell Pulsed Power Supply (ICPPS) delivered by Maxwell have been in progress at the DARHT Integrated Test Stand (ITS) for over three years. The prototype system has accumulated >35,000 shots to date with no component failures and only minor system malfunc...

A novel power supply system that directly couples pulsed high voltage (HV) pulses and pulsed 13.56 MHz radio frequency (rf) has been developed for plasma processes. In this system, the sample holder is connected to both the rf generator and HV modulator. The coupling circuit in the hybrid system is composed of individual matching units, low pass filters, and voltage clamping units. This ensures...
