Turning solid aluminium transparent by intense FLASH pulses (July 2009)

An international team of scientists from 20 institutes including HASYLAB/DESY, led by Oxford University researchers, discovered an exceptional behavior of aluminium. They observed for the first time saturable absorption of an L-shell transition in aluminium using record intensities over 1016W cm-2 at a photon energy of 92 eV. The measurements were performed at FLASH at DESY.

Prototype sucessfully tested: More energy for FLASH (July 2009)

The newest accelerator module for the FLASH free-electron laser has successfully passed the test. Now it is possible to increase the FLASH energy towards 1.2 GeV. This means that even shorter wavelengths down to 4.5 nanometers (close to the carbon K-edge at ~4. 2 nm) will be available for experiments starting next year. The module is a prototype for the European XFEL and it was partly manufactured in China. Later ...

FLASH experiment: At the limits of the photoelectric effect (April 2009)

Scientists from PTB (Berlin), Ioffe Institute (St. Petersburg), Fraunhofer Institute (Jena), Univ. Hamburg and HASYLAB/DESY discovered an exceptional behavior which concerns the fundamentals of physics. The measurements were performed at FLASH at DESY (13.7 nm).

The scientists actually wanted to develop methods for the radiometric characterization of X-ray lasers. They irradiated different gases to ...

DESY and India to collaborate in photon science (January 2009)

DESY has welcomed India as a new partner for a close collaboration in photon science at DESY´s light sources FLASH and PETRA III. On 28 January 2009, a delegation of scientists and Government representatives from India and the DESY Directorate signed a Letter of Intent to establish a scientific collaboration in nano science, nano technology, and advanced materials research. India will have access to DESY’s ...
