Resident diagnostics
The target facility is equipped with an array of diagnostic devices applicable to measurements in the optical, XUV and keV X-ray spectral regions, and to analysis of the charge state of highly stripped ions streaming out from the laser plasma. This instrumentation is available to the users for their experiments.
The laser beams may be configured to provide various backlighter geometries for both X-ray radiography experiments and optical probing.
The individual diagnostics and their basic features are summarised in the below Table.
