Abstract

The BESSY X‐ray microscopy group has developed a new full‐field x‐ray microscope with glass capillary condenser. It permits tomography and spectromicroscopy of cryogenic as well as heated samples. Correlative light and x‐ray microscopy is supported by an incorporated high resolution light microscope. Spectromicroscopy with polarized x‐rays from a helical undulator can be performed with E/ΔE = 104. With the planned BESSY High Gain Harmonic Generation Free Electron Laser (HGHG‐FEL) x‐ray imaging with ultra‐short pulses and an integral photon flux of about 1011 photons/pulse in an energy bandwidth of 0.1% will be possible. Single shot imaging with a full field Transmission X‐ray Microscope (TXM) employing a beam shaper as a condenser will be feasible with 20 fs pulses.
