Neutral Particle Beam

A projected stream of neutral particles such as deuterium or heavy hydrogen at very high particle energies and low currents.

The atoms are accelerated through electric fields as negative ions with an extra electron attached; then the electron is stripped off in passage through a gas cell, leaving a beam of neutral atoms.

Neutral particle beams must have very long dwell times on a target to produce lethal depositions of energy.
