Abstract
The generation and properties of plasmoids emitted by a conical electrodeless ring discharge are investigated. Image converter, magnetic probes, compensated magnetic loops and a retarding field analyzer were used for diagnostics. There are two mechanisms of emission depending on the initial plasma density. At low densities, when the ions can be regarded as free particles, the acceleration is caused only by the electromagnetic field at the beginning of the discharge. At high densities, when the plasma behaves hydromagnetically, the emission mechanism is governed by trapped magnetic fields in the plasma. Under certain initial conditions a plasmoid with a trapped magnetic field is generated, which exists during a time of flight of the order of 10 μs. Furthermore it is planned to accelerate this plasmoid by a special transmission line.
