The instrument allows for a wide range of surface structure investigations on solid and liquid samples. An average gradient of 16.7 MeV per meter was achieved, which is above the original design value. The quality of the accelerated electron beam met all expectations. Measurements of the magnetic and mechanical properties of the prototype undulator were satisfactory and a call for bids for the 15 m long undulator system has been made. A collaboration of specialists from 8 european countries defined the instrumentation for the characterisation of the FEL radiation.
First components are under construction.
The goal is to demonstrate the SASE principle down to wavelengths of 44 nm in the summer of 1999. The goal for the LCLS is to produce X-rays down to a wavelength of 0.15 nm. The reports on their experiments have been collected in a second section of the 1997 Annual Report. As in the preceding years, the authors are fully responsible for the content and the layout of their reports. The short time of only two weeks available for editing does not allow a critical survey on the scientific results to be presented.
