From Wikipedia, the free encyclopedia
General antiparticle spectrometer (GAPS) is a planned experiment that will use a
high-altitude balloon flying in
Antarctica to look for
antideuteron
particles from outer space
cosmic rays ,
[1] in an effort to search for
dark matter . Anti-deuterons could perhaps be produced by the annihilation of hypothetical weakly interacting massive particles (
WIMPs ).
[2] The goal of the GAPS experiment is to capture anti-deuterons in a target material, to form an
exotic atom in an
excited state . The exotic atom would quickly
decay , producing detectable
X-rays energies with
pion signature from nuclear
annihilation .
[3]
The GAPS ground test was successfully using a
particle accelerator at
KEK in 2004 and 2005. The first
high-altitude balloon test was done in June 2012 with six
Si(Li) detectors .
