Abstract: A septum electromagnet deflects and splits a particle beam. A preferred embodiment of the septum electromagnet comprises a septum conductor that divides the septum electromagnet to define first and second beam deflecting magnetic pole spaces. First and second magnetic fields are generated in, respectively, the first and second beam deflecting magnetic pole spaces by electric currents flowing through the coils associated with the septum conductor. The direction of the first magnetic field is opposite to the direction of the second magnetic field, such that a particle beam passing through the first beam deflecting magnetic pole space is angularly deflected by an amount and a particle beam passing through the second beam deflecting magnetic pole space is angularly deflected by an opposite amount.

Abstract: A foil is formed on a given substrate, then, peeled off of the substrate and floated on the water surface charged in a tank. The surface level of the water is decreased to contact the foil to a folding plate of a jug substrate and thus, fold the foil at the folding plate in two. The two surfaces of the foil opposing each other are laminated along a foil forming-supporting plate within a laminating region. The thus laminated foil is dried and annealed except the area in the vicinity of the foil forming-supporting plate, and then, cut along the folding plate, a foil acceptor and a supporting plate, to provide a stripping foil which can be supported by itself.
