The national research center Helmholtz-Zentrum Dresden-Rossendorf in Germany operates two EBIT facilities and one EBIS-A facility at its Institute of Ion Beam Physics and Materials Research. The purpose of the experiments are fundamental ion-solid interaction studies.
Three Dresden EBIT / EBIS Facilities for Research on Ion-Induced Nanostructures
The national research center Helmholtz-Zentrum Dresden-Rossendorf in Germany operates two EBIT facilities and one EBIS-A facility at its Institute of Ion Beam Physics and Materials Research.
The first Dresden EBIT was comissioned in 2003 / 2004 as part of the so-called Two Source Facility, a unique combination of the EBIT with an electron cyclotron resonance (ECR) ion source. The beams of both ion sources are directed into a UHV target chamber for experiments and irradiations with slow highly charged ions. Since both ion sources have different ranges in terms of delivered ion current and ion charge state - the ECR source produces large amounts of low charge states while the EBIT produces smaller quantities but very highly charged ions - the two sources complement each other to allow for a broad spectrum of experimental parameters for scientific investigations. The focus of current activities at the Two Source Facility is the interaction of highly charged ions with solid surfaces, especially the formation of nanostructures induced by the deposition of the potential energy of slow highly charged ions into the surface of crystalline materials.
The second EBIT was purchased as part od the "SNIPER" experiment (Surface Nanostructures by Ion's Potential Energy Release) in 2010. The complete setup consists of the ion source combined with a Wien filter for ion species separation as well as a customer-supplied deceleration lens and a target chamber with in-situ UHV-AFM/STM system. Before, HCI-produced nanostructures had to be investigated ex-situ, i.e. after ion irradiation the samples were taken out of the UHV environment and contamination with air could not have been avoided. The new setup therefore improves the experimental conditions significantly.
The newest EBIS activity at HZDR is a 500 kV acceleration platform including a Dresden EBIS-A purchased in 2015 for target irradiation at substantially higher energies compared to the EBIT facilities available at the research center.
