Web23 apr. 2024 · Ion beam charge neutralization by electron injection is a complex kinetic process. Recent experiments show that the resulting … Ion beam neutralisation. Neutralisation of the precursor ion beam is commonly performed by passing the beam through a gas cell. For a precursor negative-ion beam at fusion-relevant energies, the key collisional processes are: D − + D 2 → D 0 + e + D 2 (singe-electron detachment, with −10 =1.13×10 … Meer weergeven Neutral-beam injection (NBI) is one method used to heat plasma inside a fusion device consisting in a beam of high-energy neutral particles that can enter the magnetic confinement field. When these neutral particles are … Meer weergeven Because the magnetic field inside the torus is circular, these fast ions are confined to the background plasma. The confined fast ions mentioned above are slowed down by the background plasma, in a similar way to how air resistance slows down a … Meer weergeven • List of plasma physics articles • ITER Neutral Beam Test Facility Meer weergeven This is typically done by: 1. Making a plasma. This can be done by microwaving a low-pressure gas. 2. Electrostatic ion acceleration. This is done dropping the positively charged ions towards negative plates.
