ABSTRACT
Over almost 50 years, the most advanced applications of X-rays progressively shifted from conventional sources to synchrotron facilities (Margaritondo 1988, Margaritondo 1995, Bordovitsyn and Gushchina 1999, Margaritondo 2002, Wiedemann 2003, Willmott 2011, Winick 2012). More recently, the first X-ray free-electron lasers (FELs) were commissioned (Emma et al. 2010, Saldin Schneidmiller and Yurkov 2010, Margaritondo and Rebernik Ribic 2011, Rebernik Ribic and Margaritondo 2012a,b), starting a new trend for applications that require high peak brightness and/or very short pulses.
