The Translation, Confinement, and Sustainment Upgrade (TCSU) device is a facility to form and sustain a field-reversed configuration (FRC) in quasi-steady state using rotating magnetic fields (RMF). Recent campaigns include Ti gettering, the installa

Reducing impurity radiation and overall recycling in the Translation, Confinement, and Sustainment Upgrade (TCSU) device enabled the plasma to enter into a new, collisionless regime with temperatures well over 200 eV, substantially exceeding the radi

New evidence of relaxation in high-β plasmas has appeared in the steady-state field reversed configuration sustained by rotating magnetic fields, as signified by the self-generation of a significant toroidal field, with spontaneous transition to a h

Magnetic fusion would be significantly more attractive, and could be developed quicker, and with less expense, if it was based on engineering considerations. This paper discusses the type of systems an engineering approach leads to, and recent physic

A major concern for Rotating Magnetic Field (RMF) current drive of an FRC is that a transverse magnetic field tends to open the field lines, thus compromising confinement. In recent FRC current drive experiments it was found that thermal confinement

Relaxation in low-β plasmas has long been recognized and usually been described by the Taylor relaxation principle. Recently, relaxation has also appeared in an extremely high-β (over 85%) plasma formed by highly super Alfvenic translation of a sph

Field reversed configurations (FRCs) have been formed and sustained for up to 50 normal flux decay times by rotating magnetic fields (RMFs) in the translation, confinement, and sustainment experiment. For these longer pulse times a new phenomenon has
