MIT Preparing Experiment to Create Small Amounts of Dark Matter in the Lab
DarkLight will use the particle accelerator at the Jefferson Lab’s Free Electron Laser, in Virginia, to bombard an oxygen target with a stream of electrons with one megawatt of power. This will be able to test for these massive photons at a mass-energy of up to 100 MeV. It is hoped that this hugely powerful beam of electrons will hit the target and create this theorized form of dark matter (A’ particles). The dark matter, if it’s created, will then immediately decay into two other particles that can be (relatively) easily detected.
Sadly, it will now take a couple of years to build and test the DarkLight experiment [PDF], followed by another two years of smashing electrons into the target and gathering data. At that point, we should have a good idea about whether dark matter consists of A prime particles, or whether we’ve sadly been barking up the wrong tree. It we can pinpoint the basis of dark matter, it would be a truly monumental finding that would greatly our enhance our understanding of the universe. After that, we only have to find a way of observing and understanding the other 68% of the universe that is apparently fashioned out of dark energy…
