X-rays reveal inner structure of the Earth's ancient magma ocean

First look into magma at deep mantle conditions

15-11-2013

Scientists have for the first time peered into molten magma at conditions of the deep Earth mantle. The analysis at DESY's light source PETRA III revealed that molten basalt changes its structure when exposed to pressure of up to 60 gigapascals (GPa), corresponding to a depth of about 1400 ...

DESY light source PETRA III now has the world's sharpest X-ray eyes

Scanning X-ray microscope reaches record resolution of 10 nanometres

30-07-2012

A novel X-ray microscope at DESY offers the world's sharpest X-ray vision: Thanks to the extraordinary brilliance of DESY's X-ray source PETRA III, this microscope is able to resolve details as small as ten nanometres – which is about ten thousand times thinner than a human hair. Only few ...

Scientists measure soot particles in flight

29-06-2012

For the first time, air-polluting soot particles have been imaged in flight down to nanometre resolution. Pioneering a new technique, the international team, including researchers from DESY, snapped the most detailed images yet of airborne aerosols. “For the first time we can actually see the ...

Watching the quantum race of electrons

22-06-2012

For the first time ever, a German team of physicists has observed the race of two electrons that are liberated from atoms in the course of photoionization, i.e. under the influence of laser radiation. In order to resolve the electron’s movement during only 50 femtoseconds, scientists from Hamburg ...

Guinness World Record: X-ray laser FLASH shoots fastest movie

01-02-2012

It's official: The world's fastest movie was shot by DESY's X-ray laser FLASH in Hamburg. In its 2012 edition, the famous Guinness Book of World Records lists an interval of a mere 50 femtoseconds between two frames for FLASH. A femtosecond is a quadrillionth of a second, meaning that the two ...

The first atomic X-ray laser

27-01-2012

A group of scientists headed by Nina Rohringer from the Hamburg Center for Free-Electron Laser Science (CFEL) realized the first X-ray laser based on atoms at the Californian research centre SLAC. Using neon atoms, they generated ultra-short X-ray bursts of unique colour purity. In many cases, ...

World's best synchrotron radiation source accelerates its first beam

Clear the ring for PETRA III

21-04-2009

DESY's new synchrotron radiation source PETRA III accelerated its first beam. The positron bunches were injected and stored in the 2.3-kilometre accelerator for the first time. During future user operation, up to 960 particle bunches containing up to 10 billions of positrons - antiparticles to ...
