Abstract :
Summary form only given. We report the first observation of a "plasmoid" that is formed in a cylindrical cavity by microwave discharges of sulfur vapor at 2.45 GHz. The luminous plasmoid is generated using a sulfur vapor at a pressure of a few atmospheres. The discharge is concentrated in a luminous ball of high brightness far from the wall of the vessel containing the vapor. The emission spectrum covers the whole visible range from 380 nm to 800 nm. This is the same kind of a white light source reported previously, but it is the first time a levitated plasmoid has been observed at a high pressure.
