Description

Magnetic steerers are devices designed for small-angle corrections of charged particle beam trajectories. They are suitable for high-current applications. The operation principle is based on the deflection of charged particles in a magnetic field. Four solenoid coils are arranged outside the beamline and connected via a soft iron yoke. The setup is completed by a housing surrounding the equipment outside the vacuum including a fan to keep the coils at room temperature when operated under full power.

Standard DREEBIT magnetic steerers allow for simultaneous deflection of charged particles in horizontal and vertical direction. They feature a very compact design and can easily be integrated into existing beamline setups. The steerers were originally designed for the deflection of Ar1+ ions with an energy of 30 keV by an angle of ±10°, customer-specific solutions for other deflection angles are possible.
