The Max-Born-Institut (MBI) operates a user facility at BESSY - the German 3^rd generation high-brilliance synchrotron radiation source located in Berlin. The experiment combines laser (LR) and synchrotron radiation (SR) in order to study the dynamics of photon-induced processes at surfaces (see recent highlights).

Typically, excitation is done by laser pulses (synchronized to either single or multi bunch SR pulses), and probing is performed by time-delayed synchrotron radiation pulses. The existing surface science techniques employing synchrotron radiation such as angle-resolved UPS, XPS, photoelectron diffraction, and X-ray absorption spectroscopy open up various opportunities to probe laser-induced changes of the electronic and geometric structure.

In 2004 the MBI experiment at BESSY was relocated to the U125/1-PGM beamline. For the optical excitation of the sample we use a Ti:sapphire regenerative amplifier system (Coherent, RegA 9050), which is synchronized to the storage ring electronic master clock at BESSY.

The photoemission end station consist of a two-chamber ultra high vacuum system. For time-resolved photoemission studies two different detection schemes are used.
