Through a strategic collaboration with the Nanomaterials Lab at Swansea University, beamline users at B07 have access to an offline size-selected cluster source for sample preparation.
Cluster are produced via magnetron sputtering and thus can be made from any conductive material in circular (1-inch or 2-inch diameter) target form. After forming a charge beam with a series of ion optics, a high-transmission time-of-flight mass spectrometer allows us to select clusters from single atoms up to hundreds of thousands of atoms in size, with a mass resolution of up to 70. Ligand-free clusters can then be deposited on planar supports with a chosen coverage.
Future developments will include: the ability to deposit clusters on powder supports via a new deposition chamber (mid-2023); the transfer of samples to the beamline endstations via a vacuum suitcase (mid-2023); and preparation of clusters from non-conductive material via an RF power supply.
Please get in touch to discuss your requirements before submitting a cluster-based proposal.
