    Since their initial production in 1969, Ultracold Neutrons (UCN) have played a crucial role in probing new physics through high-precision measurements. As experimental techniques for these investigations undergo upgrades, there is a continuous need for the development of state-of-the-art UCN detectors. This presentation highlights the innovative UCN gaseous detector, GADGET, specifically designed within the framework of the n2EDM project [1].

    The talk will delve into the distinctive features of GADGET, shedding light on its design principles and operational characteristics. Notably, the discussion will emphasize recent breakthroughs in the field, particularly the results obtained from the neutron-to-hidden-neutron oscillation tests conducted during the monitoring of the UCN beam at the Institut Laue-Langevin (ILL) using GADGET [2]. These results not only showcase the detector's capabilities but also contribute to advancing our understanding of fundamental physics.
