Description
ALETHEIA, standing for A Liquid hElium Time projection cHambEr In dArk matter, is a newly established direct detection project aiming to search for low-mass DM with liquid helium-filled time projection chambers (TPCs). The project was officially launched in 2020 and has made significant progress since then. In this talk, I will mainly demonstrate that a single-phase liquid helium (LHe) TPC is technologically viable; moreover, I will slightly discuss some of the challenges in building a dual-phase LHe TPC and the preliminary solutions.
