HZB Ion trap endstation for x-ray magnetic circular dichroism spectroscopy of cold gaseous ions in a field of up to 5 T.
We offer a unique cryogenic linear quadrupole ion trap with 5 T superconducting solenoid for x-ray magnetic circular dichroism (XMCD) spectroscopy of size-selected cluster ions, molecular ions, and ionic complexes. The radio-frequency ion trap is operated in the space-charge limit for high signal-to-noise ratio. Magnetron sputtering and gas aggregation is the standard ion source, but other ion sources can be added as well.
Because of its complexity, this experimental setup requires thorough consultation with the scientist in charge. Please contact us well ahead of time to discuss experimental feasibility. This is currently the only instrument world-wide that allows performing XMCD studies of cold gas-phase ions.
Further ion sources (e.g. electrospray ionization) can be made available upon request.
