Laboratory Experiments Laboratory experiments are made both in-house, and in devices located at institutions abroad. In both cases, the projects are run in cooperation between researchers at KTH and external cooperation partners. In-house experiments, space oriented The Green Tank is a flexible device, with different discharge modes and magnetic topologies. The Triple Plasma Machine is used for studies of double layers at low neutral densities. External experiments, space oriented The Microgravity plasma experiment on the International Space Station, ISS. The Lindberg Plasma Gun, in 2006 moved from KTH to West Virginia University, USA. The VASIMR magnetoplasma rocket prototype in Houston. External experiments, applied plasma physics The HIPIMS high power sputtering magnetron at Linköping. Facilities at FOI, the Swedish Defence Reseach Agency, Grindssjön: Pulsed Explosive Driven Power Generators. Virtual Cathode Oscillators for microwave production.
