Light used to capture anti-matter

  1. Mar 15, 2009 #1
    I am planning to do a proposal about capturing anti-matter and containing it by creating a trap with light. I figured I want to use light because if I use magnetic or electric fields then I would only be able to capture charged anti-particles. My goal is to capture anti-atoms by using a light trap because i know that light can exert a force upon a particle. I need to know if this works or if anyone here can give me any suggestions or comments. Thanks.

    This is not my area of research (or particular interest, for that matter) so I cannot be of great help. But what you want to make sounds a lot like optical tweezers, so maybe searching for that will give you some inspiration.

    As of 2000, this group had plans to trap antihydrogen using a purely magnetic trap:

    Magnetic fields will exert a force on any atoms (or anti-atoms) that have a magnetic dipole moment.

    Magneto-optical traps, or MOTs, have been used to trap atoms for perhaps the last 15 years. A google search produces many hits:
