Organic semiconductors constitute an important novel class of electronic materials, especially for applications requiring low power consumption and lightweight, flexible materials. The large variety of these compounds paired with relatively low cost and ease of processing as well as the possibility to design and modify them using synthetic organic chemistry have created high expectations for...
Even after two decades of studies and debates, the mechanisms of ultrafast demagnetization remain disputed. To bring new experimental information into this field, and with the advent of femtosecond X-rays sources, I will present the results of our recent time-resolved soft X-ray resonant Magnetic Reflectivity experiment on an Fe thin film. First I will show how this technique allows probing...
Multidimensional photoemission spectroscopy (MPES) experiments using delay-line detectors generate data streams which resolve individual photoelectrons. This enables the correlation of each detected electron to the full state of the experimental apparatus. Such a detection scheme is ideal for SASE FELs such as FLASH, where the inherent intensity fluctuation and timing jitters can not only be...
News from the DESY Photon Science User Committee
The DESY Photon Science User Committee (DPS-UC) is a direct link between the users and the DESY Photon Science management to assist the communication and the exchange of information. New DPS-UC members will be nominated and elected by all users for a term of 3 years.
The User committee will take note of the needs and concerns of...
