Commissioning of Traptor, PIPE — •Karolin Mertens1, Ricarda Laarsch1, Alexander Guda2, Stephan Klumpp1, and Michael Martins1 — 1Institzut für Experimentalphysik, Universität Hamburg — 2Southern Federal University, Rostov-on-Don, Russia
The radio frequency ion trap Traptor for PIPE (Photo-Ion-Spectrometer at PETRA III) is designed to store metal clusters (and molecules) from one atom up to a number of atoms in the cluster (or molecule) with a total weight of the system of 30.000amu in maximum. Usually the production of system with such many constituents is quite difficult and the yield is very low. Thus, one of the major goals of Traptor is to improve the density of these dilute targets with higher masses to be able to perform absorption spectroscopy measurements. As PIPE is build up at the soft x-ray beamline P04 at PETRA III, DESY, photons between 250eV and 3000eV can be used for inner shell excitations e.g. of many of the transition metals. Further, using a gas mixture, not only He as buffer gas, one is able to prepare chemical reactants with the trapped clusters to examine them using either mass spectroscopy with an installed Wiley-McLaren time-of-flight ion spectrometer (iTOF) and/or absorption spectroscopy using the synchrotron radiation for fragment excitation or structural determination. Design and commissioning results of the iTOF and the operation of the trap will be shown.
