Fundamental parameters are required for accurate quantitative x-ray analysis, and the lack of recent reliable values with low associated uncertainties was pointed out during the European X-Ray Spectrometry conference (EXRS2008) in Cavtat.
Thus, within the framework of the European X-ray Spectrometry Association (EXSA), it was proposed by LNE-LNHB (France) and PTB (Germany) to start an international initiative to measure these fundamental parameters, bringing together key players from international x-ray instrumentation companies as well as various institutes from the academic sector.
In view of the challenges related to this important work, the participation of several national metrology and research institutes is essential for success. Experts on x-ray analysis should provide advice for the use of experimental facilities, ensuring best practise. Moreover, new measurements aiming at the determination of fundamental parameters should be performed by several laboratories to ensure their consistency.
Several research institutes and companies have already shown interest in participating in this initiative:
The first goals of these meetings have been :
This has been implemented in a dedicated FP roadmap document based on the input of several expert groups. In 2016 and 2017 this document was updated. Please find the version 2.0 of the FP roadmap document here.
There will be a special issue in Radiation Physics and Chemistry, showcasing the works performed within this initiative. Call for Papers
In summer 2012 a FP dedicated literature database was established. literature database
