Neutron flux and Radiochemistry: Neutron flux and Radiochemistry
- Fabrice Piquemal (CNRS)
Ambient neutrons are one of the sources of background events for
experiments studying neutrinos and searching for dark matter. This is
due to the penetrating ability of neutrons, and the fact that when
neutrons enter the detector, they can cause signals indistinguishable
from the searched ones. Preliminary measurements of neutron fluxes at
experimental sites make it possible to select the...
Construction of the Paarl Africa Underground Laboratory (PAUL) offers an opportunity for the community of austral African physicists to develop an international laboratory devoted to underground physics in the southern hemisphere. One of the main background components within PAUL will be energetic neutrons produced by cosmic rays, and neutron fluence rates ranging between 10-6 n/cm2/s to 10-5...
Currently, one of the main tools for new physics searching is the experiments at the underground laboratories, where the background is suppressed. When cosmic rays are suppressed, the main source of background is radioactive contamination of materials, facilities and measured samples. Modern level of underground experiments requires transition from mBq/kg to μBq/kg of impurities levels....
