Neutral Beam Injection
Part of powering the plasma in a fusion stellarator tokamak hybrid design involves the production of an energetic and neutral beam to enter into the closed magnetic field lines inside the vacuum vessel. The tangential and incident beam must be powered, nebulized, ionized, accelerated, focused, and then neutralized in order for this to happen. Critical to General Physics' design is the cusped mirror electric quadrupole (CMEQ) and focusing device which is an electromechanical contraption that creates a narrow beamline (on the order of millimeters) to enter the ignition region in either the L mode or the H mode. These technical specifics just mean that the entry of particles is versatile in the CMEQ system. Look for more information to come.
Schematic of Neutral Beam Injector (NBI) Cusped Mirror Electric Quadrupole (CMEQ)
General Physics is dedicated to the promise of clean, reliable, safe, and limitless energy through nuclear fusion. Neutral beam injection is a central part of the heating paradigm of the plasma. Design work is being done to develop the NBI with CNC, additive manufacturing, and hot forging.
Additive Manufacturing of NBI parts
General Physics is excited for PEEK and metal UHV safe 3D printed parts for NBI. One test cusped mirror electric quadrupole prototype has been produced. Plans are underway to construct a quadrupole test facility at USC.
CNC of NBI Component Parts
General Physics is developing a plan to create CNC machined parts for NBI that withstand neutron embrittlement, high heat flux, and high power regimes.
