7 November 2020 | Online
On 5th – 6th November 2020, Challenges project took part at the 1st International initiative on X-ray Fundamental Parameters (IIFP) that has been held online. This event has been supported by EXSA, H2020 CHALLENGES, and the EMPIR AEROMET II project. To ensure broad international participation the meeting was divided of two separate sessions from about 13:30 h to 17:30 h (CET).
The main goal of this meeting has been the discussion and assessment of existing FP values by means of appropriate tools that will be implemented subsequently. These could include dedicated study groups or other kinds of joint activities aiming at the measurement or calculation of key values and the establishment of an up-to-date database.
