    Abstract: A processing apparatus and a processing method are provided, which use a charged particle beam device that achieves defection of secondary electrons/reflected electrons at a large angle and cancels out noises of an electromagnetic deflector and an electrostatic deflector to suppress a position shift of a primary electron beam caused by circuit noises of a primary beam/secondary beam separation circuit. In the charged particle beam device that includes an electronic optical system radiating a concentrated electron beam onto a sample placed on a stage to perform scanning and captures an image of the sample, a reference signal and a signal generation unit of a voltage-source control signal applied to the electrostatic deflector generating the electrostatic deflector and a reference signal and a signal generation unit of a current-source control signal applied to the electromagnetic deflector generating a magnetic field are made common in an overlapping-electromagnetic-deflector control unit that controls a path of the secondary electrons/reflected electrons incident on a detector, and frequency characteristics and phase characteristics of the voltage control signal are coincident with those of the current-source control signal.

    Abstract: The invention relates, inter alia, to a beam guidance system for guiding a beam of charged particles with a magnetic beam deflection unit, wherein the magnetic beam deflection unit has an entry side for entry of the beam of charged particles into the magnetic beam deflection unit in a direction of entry, wherein the magnetic beam deflection unit has an exit side for exit of the beam of charged particles from the magnetic beam deflection unit in a direction of exit. A further aspect of the invention relates to an advantageous particle beam therapy system. The problem of providing improving beam properties and at the same time reducing the amount of space required is solved in that the entry side of the magnetic beam deflection unit is, at least in sections, aligned substantially parallel to the exit side of the magnetic beam deflection unit.
