Tittle:
A full-field X-ray camera for materials characterization in multidisciplinary applications
Summary:
An Italian research centre has developed a novel full-field X-ray camera for performing the space-resolved micro-XRF (micro X-ray fluorescence) analysis with high energy and high spatial resolution. The non-destructive X-ray fluorescence micro-analysis has been utilized in a number of scientific disciplines such as: medical science, material science, cultural heritage, environmental science, semiconductors. A partnership is sought for technical cooperation agreement.
Description:
Generally micro-XRF measurements are performed by scanning the sample surface with X-ray beam of small dimensions (up to the micrometric scale). In the Italian research centre a fast full-field X-ray camera technolgy has been developed for performing space-resolved micro-XRF (X-ray Fluorescence) analysis with high energy and high spatial resolution. Recently the technology has been successfully used in different multi-disciplinary applications.
The FF-XRF (Full-Field X-ray Fluorescence) consists of a 70 -Y-micro;m pinhole-collimator coupled to a 13.3 square millimeters CCD (Charge Coupled Device) detector composed of 1024x1024 pixels with a lateral size of 13 -Y-micro;m. The X-ray fluorescence is induced on the samples by using an ancillary X-ray source consisting of a medium-power X-ray tube operating at 40 kV and 1.5 mA and emitting a beam with a large divergence. The pinhole camera was designed in a compact set-up and it can be used in-situ. Possibility of performing the 2D chemical imaging to investigate materials (inorganic and organics chemical species) is one of the leading applications.

The Italian research centre is looking for partners for technical cooperation agreement in order to exploit the technology in the following potential application domains:
- cultural heritage (knowledge, restoration and conservation)
- medical science
- material science
- environmental science
- semiconductors.
Advantages and Innovations:
The main advantages of the new camera FF-XRF (Full-Field X-ray Fluorescence) are:
- faster measurements compared to standard technique which requires longer scan time of the sample surface (up to 1-2 days);
- measurements time limited to 1 hour for small samples (of 4x4 square millimeters) and to 4-5 hours for large samples (50x50 square millimeters);
- measurements can be performed in situ.
Stage of Development:
Field tested/evaluated
