X-ray microscope at nano-scale: POLLUX beamline is launched at the Swiss Light Source

23.11.2006
With the inauguration of the POLLUX beamline, the Swiss Light Source (SLS) in Villigen, Switzerland gains its tenth experimental station, providing scientists with another tool to access the nanoworld.

An X-ray lens focuses the SLS light beam to 30 nanometres. This allows the measuring of chemical maps on the nanometre scale. Such analyses serve materials science in the study of magnetism in nanostructures, which could ultimately lead to new magnetic storage systems.

Environmental science will also benefit from the POLLUX beamline. For example the study of millions of year-old pollen which holds secrets of the earth’s history and the process of fossilisation. Fine particulate matter or aerosol particles can be made visible and their chemical composition and reactivity can be analysed.

One technical challenge at POLLUX is to focus the 30 nanometre X-ray beam on the sample between the Fresnel zone plates. These X-ray lenses have the diameter of a human hair, (0.15 millimetres) and consist of many hundreds of concentric gold rings created by a nano-lithographic process.

The new beamline is a joint project of the University of Erlangen-Nuremberg and PSI. The financing of 1.6 Million Euros comes from PSI and the German Federal Ministry of Education and Research. This is the tenth beamline for the five year-old SLS, and ten more beamlines are planned.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
