Electrons near speed of light in space

  1. Nov 23, 2006 #1
    how would one go about reproducing these effects, have their been more studies since this study? Basicly it is saying that there is a way for magnetic fields to interact so that there is a "pocket" in which electrons are charged with extremly high energy and can travel at 80@ the speed of light. how can we bring this down to earth and work with it in the lab?

    Electrons are routinely accelerated to near light speed in particle accelerators here on earth (LEP for example).

    Just to expand on that, the fact that electrons are light and fundamental makes their collisions extremely clean.

    At Fermilab, the collisions are made between protons and antiprotons instead; in that case, the main collision occurs between one quark from each proton/antiproton, but there is a lot more going on around. Lower energy collisions among the rest of the particles that make each particle (other quarks and the gluons inside it) produce a lot more particles and a much more difficult environment from which to extract conclusions about what hapened.

    Yup, and this is why each new generation of colliders has always been accompanied by a new generation of linear electron accelerators. Prettty much you have <colliders -> highest energy -> new particles>, (linears -> cleanest signals -> new laws>. For example all the upper division quarks were discovered at colliders, but the anomalous scaling that led to asymptotic freedom was discovered at SLAC, a linear accelerator.

    There is an international initiative under way now to build a next-generation linear accelerator tocomplement the LHC, the new collider being built at CERN.
