Detection capability of Migdal effect for argon and xenon nuclei with position sensitive gaseous detectors

Understand

Migdal effect is attracting interests because of the potential to enhance the sensitivities of direct dark matter searches to the low mass region.

• In spite of its great importance, the Migdal effect has not been experimentally observed yet.
• A realistic experimental approach towards the first observation of the Migdal effect in the neutron scattering was studied with Monte Carlo simulations.
• In this study, potential background rate was studied together with the event rate of the Migdal effect by a neutron source.
