Description

One of the most important unsolved mysteries in physics is the possible existence of dark matter, which could account for 85% of the total mass in the universe. PICO experiment intends to detect a specific type of dark matter particle, the weakly interacting massive particles (WIMPs), via scattering on 19F nuclei from C4F10 liquid in superheated droplet detectors and from C3F8 liquid in bubble chamber detectors. I will present the physics of superheated liquid detectors, as well as calibrations with alpha particles, neutrons and gamma rays. I will discuss in particular the test beam calibrations with mono-energetic neutrons at the UdeM 6 MegaVolts Tandem accelerator. These measurements could be extended to sub-keV recoil energies and are in excellent agreement with Geant4 Monte Carlo simulations. References [1]- S.
