<b>Particle Collider Edges Forward</b><br /><br />http://news.bbc.co.uk/2/hi/science/nature/3583658.stm<br /><br />A key decision on the International Linear Collider, one of the grand scientific projects of the 21st Century, has been taken in China. <br /><br />Physicists told a Beijing conference that the multi-billion-dollar project should use superconducting technology to create its particle collisions. <br /><br />These would be high-energy impacts inside a 30km-long laboratory. <br /><br />The experiments should give scientists a deeper understanding of the materials used to construct the Universe. <br /><br />At the moment, the so-called Standard Model of particles and their interactions provides only a partial picture of the nature of the normal matter we see around us. <br /><br />Researchers know, however, the cosmos is dominated by other material which is invisible to current detection technologies. <br /><br />New light <br /><br />Europe is currently building a Large Hadron Collider (LHC) at its Cern laboratory in Geneva, Switzerland, and this is expected to open up a new research frontier when it becomes operational in 2007. <br /><br />But scientists believe they will need the ILC to carry forward their studies and expand any discoveries made at the LHC. <br /><br />The ILC is a giant undertaking that could cost upwards of $5bn. It would accelerate electrons and positrons (the antimatter version of the electron) down two 15-km-long pipes and smash them together at a central point. <br /><br />In the debris, scientists would hope to see new particles flash into and out of view. <br /><br />For example, the collider could reveal details about the long sought Higgs boson, the particle said to explain why all others have mass. <br /><br />It may also shed light on the neutralino, a particle hypothesised to interact only weakly with everything around it but which may account for much of the "dark matter

What advantage does niobium have over other material that is super-conducting very close to absolute zero? Neil

Niobium retains its superconductivity in strong magnetic fields. Other materials' superconductive properties tend to break down when magnetic fields climb too high.
