One of the main problems affecting the impact of X-ray sources worldwide is detectors performance. Much was achieved in recent years in this domain, including pan-European efforts and most notably the newly created Detector Consortium (http://www.esrf.eu/AboutUs/Upgrade/ESRFUP/WP6) of the synchrotron facilities. However, the X-ray source technology remains ahead of detectors and focusing devices meaning that the source potential is not yet fully exploited. The need for efforts in this domain is thus clear, and the advantages of multi-facility strategies (over and above the existing ones) are evident. With its JRA HIZPAD2, CALIPSO provides a response to these challenges whose effectiveness was demonstrated by similar efforts under FP7 ELISA and CALIPSO projects. Specifically, HIZPAD2 tackles the technical challenges of both high-Z pixel detectors and nanodot-based detectors.
