      abstract     = {Achromatic focusing systems for hard X-rays are examined
                      which consist of a refractive lens paired with a diffractive
                      lens. Compared with previous analyses, we take into account
                      the behaviour of thick refractive lenses, such as compound
                      refractive lenses and waveguide gradient index refractive
                      lenses, in which both the focal length and the position of
                      the principal planes vary with wavelength. Achromatic
                      systems formed by the combination of such a thick refractive
                      lens with a multilayer Laue lens are found that can operate
                      at a focusing resolution of about 3 nm, over a relative
                      bandwidth of about $1\%.$ With the appropriate distance
                      between the refractive and diffractive lenses, apochromatic
                      systems can also be found, which operate over relative
                      bandwidth greater than $10\%.$ These systems can be used to
                      focus short pulses without distorting them in time by more
                      than several attoseconds. Such systems are suitable for
                      high-flux scanning microscopy and for creating high
                      intensities from attosecond X-ray pulses.},
