Charged particles cannot be sent over large distances toward an object in space because they will be deflected by the Earth's magnetic field into a complex trajectory with a relatively short radius of curvature. Electrically neutral atoms, however, are not deflected by a magnetic field but travel through space in a straight line. Neutral particle beam (NPB) can, therefore, be aimed accurately at a target object. The most likely NPB particles will be hydrogen atoms or deuterium atoms. The NPB weapon, as considered for development in the United States, consisted of a source of negative ions, a radiofrequency quadrupole (RFQ) focusing and accelerating section, a linear accelerator to accelerate the beam to high energies, beam sensing and steering optics, and, at the last, a neutralizing section that turns the high energy negative ions into neutral atoms for the flight through space. magnetic fields; nuclear quadrupole resonance; particle beam focusing
