Abstract

Since the mid-1950s, pulsed (iron-free) high-field magnets have become a common, versatile research tool. Applications in solid state physics have promoted the development of sophisticated magnets that nowadays can achieve fields above 90 T repeatedly.

We report here another area of application for pulsed power magnet technology in combination with high-intensity lasers; namely the use of pulsed magnets as research tools in laser-based laboratory astrophysics and as effective optical devices for laser-accelerated particle beams. Pulsed power solenoids for focusing of laser-accelerated particle beams might allow for the use of these new radiation qualities in medical radiation therapy or could function as a crucial part of a compact, laser-based ion source.

The talk gives a survey of developments at Helmholtz-Zentrum Dresden-Rossendorf in portable pulse generator technology and pulsed high-field magnets, especially designed to match the requirements of different laser-plasma physics environments. The beam optical properties of a capacitor-driven air core solenoid are derived from experimental data and most recent experimental results collected within the LIGHT collaboration at the PHELIX laser system at GSI, Darmstadt are presented.
