In the laboratory of the Lehrstuhl fuer Raumfahrttechnik LRT (Astronautical Institute) of the Technische Universitaet Muenchen TUM (Technical University Munich) different types of electromagnetic launchers are being developed and operated: (1) An electromagnetic accelerator which accelerates particles in the mass range of 10-8g less than m less than 10 g to velocities up to 500 m/s; (2) an electrothermal accelerator, where particles of masses of 10-4 g less than m less than 10-1 g reach velocities up to 3 km/s; (3) a rail gun which accelerates particles in the mass range of 10-1 g less than m less than 10 g up to 3.5 km/s; (4) a plasma-dynamic launcher where particles in the mass range of 10-8g less than m less than 10-3g can be accelerated to velocities up to 20 km/s. All these systems use a fast, low inductance capacitor bank for energy storage. The first section of this paper gives a description of the four accelerator systems together with the present performance data and limitations. The current development work is discussed. In the second section the plasma diagnostics, that are used in the accelerator types (2), (3) and (4) are described together with the plasma shielding, that is necessary in the impact section.
