The Columbia Non-neutral Torus (CNT)

• The first experiment to study confinement of non-neutral plasmas in a stellarator configuration

• Ultrahigh vacuum, tabletop experiment with stellarator with circular planar coils - very simple configuration by stellarator standards

• In the design phase (PPPL collaboration)

• Recently approved for funding by US DOE
