Development of fast scanning X-ray fluorescence microscopy at the LNLS D09B-XRF beamline

A large refurbishment started in 2013 with the aim of upgrading the focusing optics of the LNLS D09B-XRF beamline. Today, the beamline comprises a new X-ray microfocusing optic based on a pair of bendable mirrors in the Kirkpatrick-Baez arrangement. The upgrading strategy also involved the migration of the control system to a NI PXI system (National Instruments Corporation), integrated with an open source EPICS/Linux platform. A new approach using a PXI system as a hardware triggering interface was developed in order to provide a continuous scanning mode of operation (”on-the-fly” scans) at D09B-XRF beamline. In this work, the main features of the LNLS XRF microprobe station as well as a description for setting up a general approach for fast scanning mode operation will be presented.
