Abstract

We present an all solid-state, high voltage pulsed power supply for inducing stable plasma formation (density {approx}10{sup 18} cm{sup -3}) in gas-filled capillary discharge waveguides. The pulser (pulse duration of 1 {mu}s) is based on transistor switching and wound transmission line transformer technology. For a capillary of length 40 mm and diameter 265 {mu}m and gas backing pressure of 100 mbar, a fast voltage pulse risetime of 95 ns initiates breakdown at 13 kV along the capillary. A peak current of {approx}280 A indicates near complete ionization, and the r.m.s. temporal jitter in the current pulse is only 4 ns. Temporally stable plasma formation is crucial for deploying capillary waveguides as plasma channels in laser-plasma interaction experiments, such as the laser wakefield accelerator.

Laser-heated capillary discharge plasma waveguides for electron acceleration to 8 GeV

Journal Article Gonsalves, A.; Nakamura, K.; Benedetti, C.; ... - Physics of Plasmas

A plasma channel created by the combination of a capillary discharge and inverse Bremsstrahlung laser heating enabled the generation of electron bunches with energy up to 7.8 GeV in a laser-driven plasma accelerator. The capillary discharge created an initial plasma channel and was used to tune the plasma temperature, which optimized laser heating. Although optimized colder initial plasma temperatures reduced the ionization degree, subsequent ionization from the heater pulse created a fully ionized plasma on-axis. The heater pulse duration was chosen to be longer than the hydrodynamic timescale of ≈ 1 ns, such that later temporal slices were more efficientlymore »« less

Radial density profile and stability of capillary discharge plasma waveguides of lengths up to 40 cm

Journal Article Turner, M.; Gonsalves, A.; Bulanov, S.; ... - High Power Laser Science and Engineering

We measured the parameter reproducibility and radial electron density profile of capillary discharge waveguides with diameters of 650 μm to 2 mm and lengths of 9 to 40 cm. To the best of the authors’ knowledge, 40 cm is the longest discharge capillary plasma waveguide to date. This length is important for ≥10 GeV electron energy gain in a single laser-driven plasma wakefield acceleration stage. Evaluation of waveguide parameter variations showed that their focusing strength was stable and reproducible to <0.2% and their average on-axis plasma electron density to <1%. These variations explain only a small fraction of laser-driven plasmamore »« less

Capillary discharge-driven metal vapor plasma waveguides

Journal Article Wang, Y; Luther, B; Berrill, M; ... - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics

We report the generation of dense plasma waveguides containing a large concentration of silver ions by means of a fast ({approx}55 ns first half-cycle) microcapillary discharge. Concave plasma density profiles with axial electron density >1x10{sup 19} cm{sup -3} were measured from discharge ablation of 330 or 440 {mu}m diameter Ag{sub 2}S capillaries with 3-5 kA peak amplitude current pulses. The dynamic of this plasma waveguide was studied with interferometry, absorption measurements, and hydrodynamic model simulations. The results are relevant to the development of efficient longitudinally pumped metal vapor soft x-ray lasers, in particular those employing transient excitation of Ni-like ions.more »« less

Observation and numerical analysis of plasma parameters in a capillary discharge-produced plasma channel waveguide

Journal Article Terauchi, Hiromitsu; Bobrova, Nadezhda; Sasorov, Pavel; ... - Journal of Applied Physics

We observed the parameters of the discharge-produced plasma in cylindrical capillary. Plasma parameters of the waveguide were investigated by use of both a Normarski laser interferometer and a hydrogen plasma line spectrum. A space-averaged maximum temperature of 3.3 eV with electron densities of the order of 10{sup 17} cm{sup -3} was observed at a discharge time of 150 ns and a maximum discharge current of 200 A. One-dimensional dissipative magnetohydrodynamic (MHD) code was used to analyze the discharge dynamics in the gas-filled capillary discharge waveguide for high-intensity laser pulses. Simulations were performed for the conditions of the experiment. We comparedmore »« less

Nonlocal-thermal-equilibrium model of a pulsed capillary discharge waveguide

Journal Article Broks, B; Garloff, K - Physical Review. E, Statistical Physics, Plasmas, Fluids, and Related Interdisciplinary Topics

Slow pulsed capillary discharges are under investigation for use as plasma channel waveguides in laser-wakefield acceleration. In this study, we present a non-local thermal equilibrium (non-LTE) plasma model with a model for the wall temperature coupled to it. This model is used to describe an example of a slow pulsed capillary discharge, and the results are compared with experimental results. The agreement is satisfactory, indicating suitability of our model. Significant deviations from LTE are found during the formation of the plasma channel. The model is also used to study the influence of the discharge current on the guiding properties. Itmore »« less
