Third-generation synchrotron radiation sources

Double-axis topography can be used at the two extremes of crystal perfection. On the one hand it can be used to probe the long-range lattice strains in very highly perfect crystals. On the other, it can be used to reveal contours of equal misorientation in much less perfect materials. As we will see in Chapter 10, it is widely used at synchrotron radiation sources and with the very large power loading in the white beam of third-generation synchrotron radiation sources. It is... 

At present FELs with output powers of several kilowatts in the infrared and several watts in the visible have been realized. The Stanford FEL reaches, for example, 130kW at 3.4 p.m, whereas from a cooperation between TRW and Stanford University, peak powers of 1.2 MW at A. = 500 mm were reported. There are plans to build FELs that cover all wavelengths in the UV down to lOnm. The spectral brilliance of these sources will be three to four orders of magnitude higher than the advanced third-generation synchrotron radiation sources. More details can be found in the literature [5.208-5.211].
