Multilayer optics is a very important field, and despite many years of development at several laboratories worldwide are still not routinely available for all spectral regions. The Japanese activity in this area is world-class, and much of that is due to the availability of a test beamline such as the one at the PF where the structures can be thoroughly tested and evaluated. As a consequence the measurements made on this beamline will form the foundation for novel applications of such mirrors, for example in cavity-type free electron lasers which are at present severely limited by mirror technology at the high energy of their range. The unique capabilities of this beamline and its end station are well suited to the work it carries out; the only upgrade that might be desirable is the provision of a range of interchangeable gratings to give enhanced performance over the whole of its photon energy range.
