Description
This session is dedicated to GEANT4 developments especially made for low counting experiments at underground laboratories.
Low-background experiments searching for dark matter, neutrinos and other rare processes heavily rely on GEANT4 in order to calibrate the detector responses, estimate the background rate and topology, predict the expected signals. Moreover, Monte Carlo simulations are extensively used in order to optimize the design of new experiments. The physics involved includes low-energy hadronic...
Many experiments operate detectors that are susceptible to fast neutron-induced backgrounds [1]. To decrease these backgrounds many collaborations, including the nuclear astrophysics community, operate their experiments in deep underground laboratories. But even in such low background environments it is critical to accurately know the environmental neutron flux.
One way to measure this is the...
The SABRE experiment (Sodium-iodide with Active Background REjection) will search for dark matter through the annual modulation in the rate of ultra-pure NaI(Tl) crystals. Dark matter signal is expected to modulate yearly because of the rotation of Earth around Sun, and thus the change of the relative velocity of the detector with respect to the dark matter halo.
The first phase of the...
