Abstract: The magnetomotive force of a current produces a magnetic field in magnetic material which encircles the current. Although magnetic material attracts a current, material having vanes repels the current because of magnetic flux lines produced between the vanes. The magnetic material is symmetrically arranged, and consists of pairs of radial, magnetic vanes connected by a magnetic member encircling the current. The magnetic member has a uniformly-distributed coil whose ampere-turns oppose the magnetomotive force of the current. The number of magnetic members is n. The angular spacing of the vanes equals 180/n. The coil ampere-turns equals l(n-1)/n, where l is the current. The guiding of the current occurs for one-half of the area of the plane on which the magnetic material is located. To obtain guiding for the other half, a second plane has magnetic material similar to that on the original plane, but rotated by the angle 180/n.

Abstract: Baffles (34) in infrared telescope (10) extend circumferentially around tube (12) of the telescope. Each of the baffles (34) has a concave, rearwardly facing curved surface (36) and a frontwardly facing planar surface (38). Baffles (34) extend from the interior wall of tube (12) in an acute angle with the optical axis (20) of the telescope, relative to front end (14) of the tube (12). This acute angle becomes greater for the baffles (34) toward rear end (16) of the telescope (10). Incoming off axis rays (44) are reflected by the planar surface (38) of the baffles (34) against the curved surface (36) of a forward adjacent baffle (34) and are reflected back and forth between adjacent surfaces (38) and (36) a number of times before being reflected back as rays (46) out of the front end of the telescope (10). Other off axis rays (40) are directly reflected as rays (42) by the planar surfaces (38) of the baffles (34).

Abstract: This invention discloses apparatus and methods to produce nuclear fusion utilizing fusible material in the form of high energy ion beams confined in magnetic fields. For example, beams of deuterons and tritons are injected in the same direction relative to the machine axis, but the deuteron velocity is sufficiently greater than the triton velocity so that the deuterons overtake the tritons at a relative velocity which produces a high fusion reaction cross section. The momentum of the deuterons is approximately equal to the momentum of the tritons so that both types of ions follow essentially the same path. Thus, the deuteron and triton beams, together with electrons for space charge neutralization, constitute a "moving-plasma", in which fusion reactions occur. Various alternative magnetic field configurations are described for confinement of the high energy ion beams. Methods are given for the starting and steady-state operation of the invention, based on change-of-charge-state trapping of injected material.

Abstract: This invention discloses apparatus and methods to produce nuclear fusion utilizing fusible material in the form of high energy ion beams confined in magnetic fields. For example, beams of deuterons and tritons are injected in the same direction relative to the axis of a vacuum chamber. The ion beams are confined by the magnetic fields of long solenoids. The products of the fusion reactions, such as neutrons and alpha particles, escape to the wall surrounding the vacuum chamber, producing heat. The momentum of the deuterons is approximately equal to the momentum of the tritons, so that both types of ions follow the same path in the confining magnetic field. The velocity of the deuteron is sufficiently greater than the velocity of the triton so that overtaking collisions occur at a relative velocity which produces a high fusion reaction cross section.
