A common initiative for the research into the physics and technology of a flyer plate electromagnetic accelerator has been started at AWE, Aldermaston and Loughborough University. Two electromagnetic accelerators have been constructed and tested: AMPERE, a 120 kJ / 40 kV capacitor bank system at AWE and QUATTRO a 100 kJ/30 kV capacitor bank system at Loughborough Pulsed Power Laboratory. Two numerical...
A joint program involving the study and practical performance of a foil-flyer electromagnetic accelerator has recently been initiated by Atomic Weapons Establishment, Aldermaston, and Loughborough University. As an initial phase of the work, both 0-D and 2-D numerical models for the foil-flyer accelerator have been developed. The 0-D model, although very crude, is capable of providing an insight into...
An essential requirement arising in the research programs at both Loughborough University (UK) and the University of Pau (France) into a non-invasive pulsed electric field (PEF) food processing technique is the reliable measurement of the intense fast transient electric fields occurring in the near field of an antenna immersed in water. Field measurements are conventionally performed using either...
A high-energy pulsed-power source based on a 30 kJ capacitor bank has recently been developed at Loughborough University. An H-bridge circuit configuration is used, with one pair of the diagonally opposite arms comprising a high-voltage ballast inductor and the other pair an exploding wire array capable of generating voltages up to 250 kV. The two centre points of the H-configuration provide the output...
In addition to its many defence applications, pulsed power is becoming widely used in civilian areas such as pulsed electric field (PEF) industrial food processing, pollution control, biology and medicine, when a reliable, simple and repetitive table-top high-power source is often required. As part of an ongoing research programme into the technology involved, Loughborough University has developed...
A novel and non-invasive pulsed electric field (PEF) technology for use in the food processing industry is under development at both Loughborough University (UK) and the University of Pau (France). The technology uses an antenna coupled to a high-voltage pulsed generator to produce short duration pulses of very intense electric field strength. In the Loughborough scheme, a Tesla transformer charges...
