SuperKEKB: back on track – better than ever

Particle accelerator SuperKEKB in Japan starts commissioning phase
After five years of upgrade work, the particle accelerator SuperKEKB at the Japanese research centre KEK has taken up operation again. In the first days of March 2016, the first stable beams of electrons and positrons were turning in the 3-kilometre-long ring. This is an important step towards producing particle collisions inside the similarly refurbished detector Belle II, which is still under construction by an international collaboration and will start operation in 2017. In the unprecedented large number of collisions of electrons and their anti-particles, physicists want to produce large numbers of B and D mesons as well as tau leptons. By studying very rare processes they hope to find new physics beyond the standard model of particle physics as well as an answer to the question why the universe consists of largely of matter even though equal amounts of matter and antimatter should have been produced in the Big Bang.

Better solar cells, superconductors and hard-drives

By Bénédicte Huchet. Published on 28 April 2014 in:
April 2014, News, , ,

Using DESY’s light sources, scientists have opened a new door to better solar cells, novel superconductors and smaller hard-drives.
The research reported in the scientific journal Nature Communications enhances the understanding of the interface of two materials, where completely new properties can arise. With their work, the team of Prof. Andrivo Rusydi, from the National University of Singapore, and Prof. Michael Rübhausen, from the Hamburg Centre for Free-Electron Laser Science, have solved a long standing mystery in the condensed matter physics…

New milestone reached for the European XFEL construction

By Jorge Rivero González. Published on 26 July 2013 in:
July 2013, News, , , ,

On June 2013 an important milestone was reached for the European X-ray free-electron laser [XFEL] with the completion of its underground portion. Located in the Hamburg area (Germany), the European XFEL is one of the largest and most ambitious European projects to date. Starting full operations in 2016, the European XFEL is expected to generate intensive, ultrashort X-ray flashes that will open up entirely new areas of research with X-rays that are currently inaccessible. Organisations from 12 European countries…

DESY reveals hidden paintings of Rembrandt

By Bénédicte Huchet. Published on 29 January 2013 in:
January 2013, News, , , , ,

Underneath the “Old Man in Military Costume” painted by the Dutch artist Rembrandt in the years 1630/31, investigations spotted another portrait which was only faintly distinguishable with all applied technologies. An international team of scientists now used a detailed mock-up to test different methods to look beneath the original painting at DESYs X-ray source DORIS and at the National Synchrotron Light Source [NSLS] of the Brookhaven National Laboratory [BNL] in the United States, as well as with a mobile X-ray scanner. The results are published as the cover story of the “Journal of Analytical Atomic Spectrometry” [JAAS] of the British Royal Society of Chemistry…

PETRA III X-ray microscope reveals to record resolution

By Ian Randall. Published on 28 August 2012 in:
August 2012, News, , , , ,

PETRA III is now the world’s most advanced X-ray microscope, with a record-breaking resolution of 10 nanometres. The light source – located at the Deutsches Elektronen-Synchrotron [DESY] – can see down to structures ten thousand times thinner than a human hair.

The apparatus – which is already available to users – has many possible applications, including such uses as: imaging the structure of microchips, investigating carbon nanotubes and studying the chemistry of catalyst nanoparticles…
