soft X-ray spectral range

ABSTRACT
BESSY plans to construct a linac-based single-pass FEL as an addition
to its existing third gen-eration storage-ring based light-source. The
project aims to obtain a SASE FEL user-facility that covers the VUV and
soft X-ray spectral range (_w 1 keV). At present the design-stage
is funded for a period of three years and consists of a collaboration between
BESSY, DESY, the Hahn-Meitner-Institute in Berlin, and the Max-Born institute
for non-linear optics in Berlin.
The BESSY FEL focuses on optimization of the FEL as a user light-source,
both with respect to its capabilities and in its performance: e.g., stability,
seeding options of the SASE FEL, wave-length-tunability, synchronization
with external laser sources and, on a longer time-scale, the generation
of ultra-short (< 50 fs) optical pulses.
The talk presents details on the project goals, details on the expected
performance of the FEL, the design strategy, and a short overview of types
of experiments foreseen by potential users.
