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.

Electromagnets for and method of deflecting and splitting a particle beam

An injection apparatus both for positive and negative ions comprising: a first, a third and a fourth bump magnets arranged in order on a circulation orbit, a second bump magnet arranged on said circulation orbit between the first and the third bump magnets so as to maintain a given position relative to the circulation orbit and a carbon film arranged between the second and the third bump magnets, wherein the second bump magnet is afforded with both of respective functions of a bump magnet and a septum magnet, the second bump magnet is operated as the bump magnet upon the injection of a negative ion beam, while the second bump magnet is operated as the septum magnet upon the injection of a positive ion beam.
