Quadrupole Beam Bender
Quadrupole Beam Bender
Description
The DREEBIT Quadrupole Beam Bender is an ion optical device designed to bend charged particles of the electric charge q with kinetic energies of up to 25 kV · q by an angle of 90°. The deflection is realized by quarter-pipe electrodes set up perpendicularly to the direction of the incoming ion beam in a typical electrostatic quadrupole arrangement.
With this design, the quadrupole beam bender can be used to guide a beam towards up to three different beamline sections downstream from the quadrupole chamber (directions ±90° and straight). Additionally, the quadrupole is equiped with lenses to correct the shape of the beam after ±90° deflection.
The beam deflection can be set continuously by using standard power supplies or the quadrupole can be operated in pulsed mode. Therefore, a high voltage pulser with built-in power supplies has been developed which is available as optional equipment to the quadrupole beam bender.
