The milliQan Experiment: Search for milli-charged Particles at the LHC

Understand

Recently, a search for milli-charged particles produced at the LHC has been proposed.

• The experiment, named milliQan, is expected to obtain sensitivity to charges of $10^{- 1} - 10^{-3}e$ for masses in the 0.1 - 100 GeV range.
• The detector is composed of 3 stacks of 80 cm long plastic scintillator arrays read out by PMTs.
• It will be installed in an existing tunnel 33 m from the CMS interaction point at the LHC, with 17 m of rock shielding to suppress beam backgrounds.
