Quadrupole deflector of the double Penning trap system MLLTRAP [*] — •Eva Gartzke, Veli Kolhinen, Dietrich Habs, Jürgen Neumayr, Christian Schürmann, Jerzy Szerypo, and Peter Thirolf — Fakultät für Physik, LMU München and Maier-Leibnitz Laboratory, Am Coulombwall 1, 85748 Garching, Germany
A cylindrical double Penning trap has been installed and successfully commissioned at the Maier-Leibnitz Laboratory in Garching. This trap system has been designed to isobarically purify low energy ion beams and perform highly accurate mass measurements [1].
An electrostatic quadrupole deflector has been designed and installed at the injection line of the Penning trap system enabling a simultaneous use of an online ion beam with reference ions from an offline ion source. Alternatively two offline sources can be used concurrently e.g. an α recoil sources providing heavy radioactive species (e.g 240U) together with reference mass ions (which in the future will be e.g. a carbon cluster ion source).
The bender has been designed for beam energies up to 1 keV with q/A ratios 1/1-1/250.
This presentation will show the technical design and the operating parameters of the quadrupole beam bender and its implementation at the MLLTRAP system.
