A NEW LARGE AREA TOF MASS SPECTROMETER — •Ralf Srama¹, Michael Rachev², Stefan Helfert³, Sascha Kempf¹, Georg Moragas-Klostermeyer¹, Anna Mocker¹, Frank Postberg¹, and Eberhard Grün¹ — ¹MPI-Kernphysik, Heidelberg, Germany — ²CALTECH, Pasdena, USA — ³Helfert Informatik, Mannheim, Germany

Based on experience with current space dust instruments on-board interplanetary missions, a novel Dust Telescope is being developed. A dust telescope is a combination of a dust trajectory sensor and a mass analyzer. The trajectory sensor is used to determine the speed, mass and trajectory of interplanetary and interstellar dust grains. In contrast, the mass analyzer provides the elemental composition of individual grains. Here, we report about the successful tests of the large area mass analyzer (LAMA) at the dust accelerator of the Max Planck Institute for Nuclear Physics in Heidelberg.
