摘要
Studying non-neutral plasma is a long and established field however the majority of these studies utilized cylindrical traps. The newly constructed Lawrence Non-Neutral Torus (LNT) H apparatus will study non-neutral plasmas in toroidal geometry. The LNT II features an improved toroidal magnetic field magnitude (similar to 1 kG) and base vacuum pressure (<10(-9) Torr) from the previous apparatus. A segmented Au-plated Al electrode shell contributes to the reduction in field asymmetries and enables enhanced diagnostics. Additionally, the electron source is located on a retractable bellows for study of confinement dynamics in a complete torus. Confinement times on the order of 1 second would represent more than an order of magnitude improvement over measurements made with the previous apparatus.
