We believe that our results can give some enlightenment on the future laser-plasma based accelerators. At many places worldwide new laser installations and particle or heavy ion accelerators are being built to address this problem. Therefore, these beam parameters are scalable over a wide range of experimental conditions which is useful for the design of laser accelerators for applications. Both accelerators were bought without consultation or further analysis and without having prepared physicists beforehand to use them.

The presence of a longitudinal field provides the additional possibilities to control the dynamic processes in the coaxial plasma accelerators. Plasma accelerators at the energy frontier and on tabletops. High current density ion sources for heavy ion fusion accelerators. The negative ion pressure requirements on the accelerators, transpor t, focusing, and drift-compression regions should be almost identical to the pressure requirements for positive heavy ion beams. We propose to use this effect as a plasma diagnostic tool, utilizing monoenergetic, well-collimated electron or proton beams produced either by femtosecond laser plasma interactions or by accelerators. In the future, such opportunities would allow the plasma accelerators to be used in applications such as electric jets in space as well as in thermonuclear installations. During this period megaampere pulsed power accelerators made their appearance and gave rise to the era of pulsed power driven z-pinch plasmas as potential sources of intense radiation. The motion of charged particles in spatially varying magnetic fields has received a great amount of attention because of its relevance to plasma fusion devices, particle accelerators and astrophysics.

Since the invention of particle accelerators in the 1930s, scientists have continuously upgraded their design and performance to increase the energy yields achievable. As with all accelerators, the ions are kept enclosed in evacuated chambers to ensure no reactions occur with surrounding particles.
