Characterization of Gun Plasma Penetrated Into a Steady State Plasma Device

Characterization of a pulsed plasma formed with a plasma gun device was performed. The averaged electron density was measured with an interferometer system using a Zeeman laser at 633 nm. It was found that the plasma with the density of ~ 10 22 m -3 was successfully formed. The temporal evolution of...

Description
Summary:Characterization of a pulsed plasma formed with a plasma gun device was performed. The averaged electron density was measured with an interferometer system using a Zeeman laser at 633 nm. It was found that the plasma with the density of ~ 10 22 m -3 was successfully formed. The temporal evolution of the plasma was observed with a fast framing camera. It was found that the shape of the plasma was significantly varied temporally. From the intensity profile, the vertical emission profile was obtained using Abel inversion. The emission profile had a flat top shape with the radius of ~ 20 mm, and gradually decreased with the radius. The penetration behavior of the gun plasma across the magnetic field was observed.
