ST Path to Fusion: First Results from ST40
Description
ST40 is a high field spherical tokamak with a major radius of 40cm at Tokamak Energy. The device utilizes a 4m tall stainless steel vessel with copper toroidal field coils which produce magnetic fields up to 3T. ST40 uses a novel merging-compression method for plasma start-up. The objective of ST40 is to demonstrate burning plasma conditions in a high-field, low aspect ratio spherical tokamak.
