Abstract: A pulse transformer arrangement (100) is built from an uncut pulse transformer core (110) and at least one foil winding (120-A, 120-B) (each) comprising multiple insulated conducting strips arranged around the core and ending in foil winding terminals to form multiple independent primary windings. This new design principle has several advantages. Making the winding(s) of foil eliminates the need to cut the core, because of the ease of insertion of the foil winding(s) onto the core. The work to set up a plurality of primary windings is significantly reduced. In addition to the elimination of the costs for cutting the core, this also brings the further advantages of reduced DC reset current, reduced risk for electrical shorts and avoidance of excessive losses due to potential high frequency AC resistance problems.

Abstract: An arrangement and a method for irradiation of products by charged particles. The arrangement comprises a particle acceleration device and a radiation chamber, in which the products are irradiated from at least two sides, by that the particle beam is deflected with a scanning magnet and redeflected with redeflection magnets. The particle beam impinges on the products substantially parallel to the main normals of the surfaces of the products, which normals are positioned substantially perpendicular to the direction that the radiation axis has immediately before the deflection. An absorption means comprising a particle stopper is arranged in the space between the pole pieces of the redeflection magnets. A transport device for double-sided irradiation transports the products, which during transport are fixed to the transport device, through the irradiation arrangement.

Abstract: Method and apparatus in a race-track microtron for storing an energy-rich electron beam. Electrons are accelerated by repeatedly passing them through a linear accelerator that is arranged between two bending magnets, which change the electrons path so that they repeatedly pass through the linear accelerator. The electrons thereby move in orbits (3 . . . 8) with a race-track-like configuration and have successively larger orbits. A deflecting magnet (9') and a septum magnet (9") are arranged in conjunction with the greatest orbit (8). The characteristic features of the invention is that the microtron has a storage ring (10) closed in itself, for accelerated electrons. The storage ring is situated outside the septum magnet (9") and in the pole gap of each bending magnet (6, 7). A kicker magnet (16) is arranged in the storage ring (10).
