5. Real time Migdal effect searches with deep learning-based object detection

A number of direct dark matter detection experiments invoke the Migdal effect to extend their sensitivities to sub-GeV masses; however, this effect has yet to be observed in nuclear scattering. The Migdal in Galactic Dark mAtter expLoration (MIGDAL) experiment aims to, for the first time, directly image and characterize the Migdal effect in nuclear scattering by recording high statistics of...

3. PMT analysis for Negative Ion Drift and 3D reconstruction

CYGNO/INITIUM is a directional TPC detector for low energy rare event searches with the purpose of detecting low mass (0.5-50 GeV/c2) WIMPs and performing solar neutrino spectroscopy. This project establishes itself by its strong directionality capabilities, the use of gaseous He:CF4 at atmospheric pressure, and optical readout.

In CYGNO detectors, the amplification is achieved by a stack...

7. Improving understanding of negative ion avalanche formation (to be confirmed)

Lachlan McKie (Australian National University)

Gaseous Time Projection Chambers (TPCs) have distinct advantages in a WIMP dark matter search, as well as other fields, owing to their ability to sense the highly directional nature of the signals [1,2]. How- ever, increasing the detector scale has presented technical challenges, especially electron diffusion over large drift distances. Electronegative TPC gases, such as SF6 [3] form negative...
