Ultrawideband (UWB) systems that radiate very high-level transient waveforms and exhibit operating bandwidths of over two decades are now in demand for a number of applications. Such systems are known to radiate impulse-like waveforms with rise times

A detailed KrF amplifier model is first benchmarked against new data and then used to design higher-energy modules with segmented pumping. It is found that segmentation with unpumped regions does not carry with it any penalty in efficiency because th

Nike is a recently completed multikilojoule krypton-fluoride (KrF) laser that has been built to study the physics of direct-drive inertial confinement fusion. The two final amplifiers of the Nike laser are both electron-beam-pumped systems. This pape

Starting in 1984, studies have been made of 15-65 MV, 4 MJ, 9-16 ns ion drivers for the LIBRA ICF reactor. The Helia approach was adopted. Design options and general design considerations are discussed. A recent 30 MV design is described that consist

We have performed a conceptual design of a 6 MV IVA with cells that are directly driven from individual Marx/peaker circuits. The present design assumes use of the RITS IVA cell parameters, driving a negative polarity vacuum coax, and a load impedanc
