The XENON experiment is a 3500kg liquid xenon (LXe) detector to search for Dark Matter. It is a dual-phase time projection chamber (TPC) housed at the INFN Laboratori Nazionali del Gran Sasso. Particles recoiling in LXe produce photons (scintillation) and electrons (ionization).
The photons are detected as the “S1” signal with 248 3-in. photomultiplier tubes (PMTs) positioned above and below the LXe target. Electric fields drift the electrons upward and extract them into gaseous xenon, where electroluminescence produces a secondary scintillation “S2” signal.
In most analyses, the ratio between S1 and S2 differentiates electronic recoils (ERs), caused by β particles and γ rays, from nuclear recoils (NRs), caused by neutrons or some DM particles. The interaction position, reconstructed from the S2 light pattern and the time difference between S1 and S2, discriminates DM candidates from most external radioactive backgrounds.
