Abstract:
A septum electromagnet for deflecting a particle beam, comprising:first and second coils; a septum conductor positioned to divide a septum electromagnet into first and second beam deflecting magnetic pole spaces, the first beam deflecting magnetic pole space associated with the first coil and the second beam deflecting magnetic pole space associated with the second coil; the first coil, when conducting an electric current, generating a first magnetic field having a first field direction in the first beam deflecting magnetic pole space, and the second coil, when conducting an electric current, generating a second magnetic field having a second field direction in the second beam deflecting magnetic pole space, the first and second field directions being opposite to each other; and the first magnetic field having a first magnetic field strength and operating to angularly deflect in a first deflection direction a first particle beam traveling through the first beam deflecting magnetic pole space, and a second magnetic field having a second magnetic field strength and operating to angularly deflect in a second deflection direction a second particle beam traveling through the second beam deflecting magnetic pole space, the first and second deflection directions being opposite to each other.
