Tri Alpha Energy is a private company that is developing a fusion power device called the colliding beam fusion reactor (CBFR). The company was founded in 1998 and is headquartered in Tustin, California. The CBFR uses a field-reversed configuration (FRC) to contain the plasma, which is heated by neutral beam injection and radio frequency heating. Tri Alpha Energy has received funding from a variety of sources, including Microsoft co-founder Paul Allen's Vulcan Capital, Goldman Sachs, and the Russian government-owned nuclear corporation Rosatom. The company has not yet achieved net energy gain, but has reported progress in plasma confinement and stability.
