ID21

Synopsis

ID21 is focusing its activity on the in-vacuum scanning X-ray microscope (SXM). After the present commissioning following the EBS shutdown, the transfer the BLISS control system and the installation of a new DCM, the microscope should offer a beam of ~ 0.3µm Vx0.7µm H for 2D µXRF (elemental maps) and µXANES (chemical speciation in 0D, 1D and 2D) in the energy range 2-10 keV. An additional nanoscope is currently under design, that should be commissioned in 2021.
Status:  open
