Abstract
Certain configurations of devices are described herein that include a DC multipole that is effective to doubly bend the ions in an entering particle beam. In some instances, the devices include a first multipole configured to provide a DC electric field effective to direct first ions of an entering particle beam along a first internal trajectory at an angle different from the entry trajectory of the particle beam. The first multipole may also be configured to direct the ions in the first multipole along a second internal trajectory that is different than the angle of the first internal trajectory of the particle beam.
