We report on further developments of the optical design of the Russian -Ger
man soft X-ray beamline at BESSY II. Ray-tracing calculations reveal state-
of-the-art characteristics of the modified layout. Resolving power up to 25
000 and photon flux up to 3 x 10(10) photons/s/100mA will be available for
spectroscopic experiments. Technical details of operation of the precision
mechanics used for fine adjustment of the first mirror are presented. (C)
