The intense X-rays from SOLEIL will be used for a range of experiments in physics, chemistry and biology. The machine is expected to come on-line in 2005. According to Schwartzenberg, the French gover...
In harmonic generation a short pulse of intense radiation is focussed into a gas of atoms. The laser-atom interactions are highly nonlinear, and a number of the input photons effectively combine to ge...
However, the resolution possible with scanning near-field optical microscopy (NSOM), as this approach is called, is essentially limited by the size of the aperture. To improve the resolution it is nec...
Klaus Dieter Liss from the European Synchrotron Radiation Facility in Grenoble, France, and colleagues have created a cavity that traps X-ray photons between two thin plates of silicon (Nature 404 371...
Stirling is no stranger to Grenoble, having worked at the nearby Institut Laue-Langevin (ILL) neutron source for 14 years, and later chairing the ILL scientific council. He currently uses X-rays from ...
Construction of the new synchrotron is expected to take about five years, and it will cost about £550 m to build and operate the machine over its 20 year lifetime. The Wellcome Trust will contrib...
Quantum particles such as electrons can be in a superposition of two or more quantum states. This means that an electron can, for instance, be in two places at the same time. However, classical object...
Physicists have tried for years to develop a beam of atoms that could be focused as easily as electrons and photons. The helium atoms are fired at 1 km/s through a micron diameter nozzle past a set of...
