Abstract
The new transmission X-ray microscope (TXM) at BESSY II is the first one using soft X-rays in the
water window region at an undulator beamline. For this, the condenser monochromator has been adapted to the
highly collimated X-ray beam of the undulator U41. This is done by using a rotating condenser (RK) which can
match the numerical aperture of any micro objective zone plate [1]. The actual setup of the TXM is given in this
report. Several beam diagnostic instruments have been incorporated into the beamline and the microscope to adjust
the optical elements and to study the behaviour of the complete system. The results of the characterization done so
far will be presented as well as first images of applications will be shown.
