The aim of this series of annual meetings is to intensify scientific exchange, stimulating new collaborations between these scientific communities. Now a team from Brazil has analysed at BESSY II which processes occur during the relevant phase transition from one shape to the other. A photoelectron microscope has also been developed which is particularly important for nanoscopic structures. At the BESSY II storage ring, a team has shown how the helicity of circularly polarized synchrotron radiation can be switched faster - up to a million times faster than before. Abstract.
