The status of the AMS device for medium mass isotopes at the Cologne University — •Susan Herb, Stefan Heinze, Markus Schiffer, Gereon Hackenberg, Claus Müller-Gatermann, Alexander Stolz, and Alfred Dewald — Institute of Nuclear Physics, University of Cologne, Cologne, Germany

In order to improve the features of the new mass spectrometer at the Cologne 10 MV FN accelerator we started a detailed investigation of the actual beam optics by installing beam profile monitors at four locations along the beamline. The beam path inside the gas-filled 135^∘ bending magnet is inspected by use of multiple array of solar cells which were mounted at different angles of the magnet and moved along the focal plane. In addition it is intended to measure the flight time through the magnet by a MCP start detector in front and a Silicon detector after the magnet.

In this contribution we will report on the actual performance of the system and the results of the beam profile measurements.
