Cooling of highly charged Ions in the HITRAP cooler Penning Trap — •Bernhard Maaß1,2, Zoran Andelkovic2, Svetlana Fedotova2, Frank Herfurth2, Nikita Kotovskiy2, Claude Krantz3, Denis Neidherr2, Wilfried Nörtershäuser1, Wolfgang Quint2, and Jochen Steinmann2 — 1TU Darmstadt — 2GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — 3MPI-K Heidelberg
The HITRAP cooler Penning trap will be used for cooling and storing of bunches of up to 105 ions as heavy as U92+. The aim is to use both electron cooling and resistive cooling to cool ions down to values below 1 meV. Bunches of 1010 electrons can be injected into the trap from an electron source installed downstream. The electrostatic potentials of the trap electrodes will be arranged to form a nested trap to capture both, ions and electrons, simultaneously inside the trap. In the last years, the trap has been investigated by measuring ion and electron storage times. Based on the gained experience from these experiments, the trap is now reassembled with various improvements to further increase the trapping and cooling performance. An installed test ion source provides the opportunity to test and align the renewed setup.
