“…The Electra main amplifier (shown in Fig. 1) has been described previously [8]. Briefly, two separate pulse power systems provide counter-propagating electron beams, each 500 keV, 100 kA and a flat top pulse width of 100 ns over an area of 30 × 100 cm 2 .…”

The United States Naval Research Laboratory is developing an electron beam pumped krypton fluoride laser technology for a direct drive inertial fusion energy power plant. The repetitively pulsed krypton fluoride laser technology being developed meets the fusion energy requirements for laser beam quality, wavelength, and repetition rate. The krypton fluoride laser technology is projected, based on experiments, to meet the requirements for wall plug efficiency and durability. The projected wall plug efficiency based on experiments is greater than 7 percent. The Electra laser using laser triggered gas switches has conducted continuous operation for 90,000 shots at 2.5 Hertz operation (ten hours). The Electra laser has achieved greater than 700 Joules per pulse at 1 and 2.5 Hertz repetition rate. The comparison of krypton fluoride laser performance with krypton fluoride kinetics code shows good agreement for pulse shape and laser yield. Development and operation of a durable pulse power system with solid state switches has achieved a continuous run of 11 million pulses into a resistive load at 10 Hz.

“…Electron beam pumped lasers are the few plasma devices which used electron beams injected into dense gas targets already in the last century. They are normally powerful machines with hundreds of Kilovolts acceleration voltage and Kiloamperes beam currents sent e. g. through large area titanium foils [17,18]. Some smaller, table top devices with metal entrance foils do exist and are also used for laser experiments [19].…”

Abstract. Electron beams with a particle energy of typically 12 keV are used for collisional excitation of dense gases. The electrons are sent through ceramic membranes of only 300 nm thickness into gas targets. Excimer light emission from the pure rare gases and from gas mixtures are studied for the development of brilliant VUV and UV light sources. The application of the technology for gas kinetic studies is described and its potential for building very small electron beam pumped lasers is discussed.

“…In applications, a lot of facilities can be simplified as the HES module including two capacitors and a transformer shown in Fig. 2 [9][10][11][12][13][14][15][16]. Switch S1 has ability of closing and opening at different time.…”
