The Ion Beam Facility has seven beamlines, of which three are in use. Beamline 1 is linked to Magnum-PSI allowing for in situ world’s highest plasma-flux exposure and ion beam analysis of (near) surface composition. Beamline 5 leads to Upgraded Pilot-PSI (UPP) allowing for in situ and operando studies of materials under mid-flux plasma exposure. Beamline 7 goes to an ex situ ion beam analysis chamber called IBAS. The tables below show the parameters of the three chambers in use. Final parameters depend on the combination of energy, ions, target, setup, techniques and the experience of the experimentalist.
Beamline 1: Magnum-PSI / TEAC
The beamline directly connected to the linear plasma device Magnum-PSI allows for in vacuo determination of the chemical composition and changes in the near surface of materials as a result of plasma exposure. After plasma exposure, the target can be retracted under vacuum into the Target Exchange and Analysis Chamber (TEAC) and analyzed with surface analysis equipment.

Beamline 7: ion beam analysis (IBAS)
The beamline connected to a local, in-house user station is an ion beam analysis station (IBAS) that allows for interactive development of novel materials. This user station will be updated in 2023.
