Overview, recent results, R&D activities, and futre plans of NEWAGE and CYGNUS-KM will be presented.
The COHERENT collaboration was the first to observe coherent elastic neutrino-nucleus scattering (CEvNS) at the Spallation Neutron Source at Oak Ridge National Laboratory (TN, USA) in 2017. The SNS is a pulsed pion decay-at-rest neutrino source with a well-known spectrum of low-energy neutrinos.
Today, the collaboration operates several detectors measuring CEVNS and neutrino-charged-current...
Negative ion (NI) gas mixtures offer many benefits for directional detection, including low (near-thermal) diffusion and the possibility of adding spin-dependent targets for dark matter (DM) searches. However, the unforeseen benefit of multiple NI species allowing for fiducialization of the drift coordinate in time projection chambers (TPCs) might allow for uses beyond directional detection. ...
Nitrogen vacancy (NV) centers in diamond have been identified as a promising future platform for directional detection of weakly interacting massive particle (WIMP) dark matter. A WIMP particle induces nuclear recoil in the diamond, resulting in a direction-dependent sub-micron damage track. This damage track induces crystal stress variations which shift the energy levels of NV centers,...
The recent progress of the NEWSdm experiment will be reported.
The NEWSdm experiment is designed to search for dark matter with directional sensitivity at the Gran Sasso laboratory. Nano Imaging Tracker (NIT) used in the NEWSdm experiment is a super-high resolution nuclear emulsion detector. This extremely high spatial resolution makes NIT the unique solid tracking detector capable of determining the direction of nuclei with a track length of 100 nm,...
The Recoil Directionality project (ReD) within the Global Argon Dark Matter Collaboration aims to characterize the response of an argon dual-phase Time Projection Chamber (TPC) to neutron-induced nuclear recoils (NRs) and to measure the charge yield for low-energy recoils. This measurement is crucial to improve the sensitivity of future low-mass studies. The charge yield is a critical...
Levitated optomechanics provides a novel platform to test fundamental physics. One such application provides a unique directional dark matter direct detection technique to explore alternative parameter space to that being investigated by large scale experiments deployed underground. We present progress towards an experiment built at University College London, capable of resolving collisions in...
We present the research plans on the development an Optical Time Projection Chamber (O-TPC) - a multi-purpose gaseous radiation-detector system, as part of the SARAF infrastructure. SARAF Phase II accelerator will provide unique capabilities for neutron-induced reactions, offering intense primary beams for high neutron flux, and tunable neutron energy.
The Negative Ion Drift (NID) gas SF₆ has favourable properties for track reconstruction in directional Dark Matter (DM) searches utilising low pressure gaseous Time Projection Chambers (TPCs). However, the electronegative nature of the gas means that it is more difficult to achieve significant gas gains with regular Thick Gaseous Electron Multipliers (ThGEMs). Typically, the maximum attainable...
SF6 has become of interest as a negative ion drift gas for use in directional dark matter searches. However, as for other gas targets in such searches, it is important that contamination gases can be removed. This includes radon gas contamination that can decay, producing unwanted background events able to mimic genuine signals, but also outgassing and leaking introduce contaminants such as...
Low pressure gaseous Time Projection Chambers (TPCs) are a viable technology for directional Dark Matter (DM) searches and have the potential for exploring the parameter space below the neutrino fog. Gases like CF4 and SF6 are advantageous because they contain Flourine which is predicted to have heightened elastic scattering rates with a possible Weakly Interacting Massive Particle (WIMP) DM...
The talk will include Ionization Quenching Factor measurements with COMIMAC, electron-nuclear recoil discrimination and many other items related with.
We propose a novel method to determine the mass scale of ambient dark matter that can be generally applied to the (at least effectively) two-dimensional direct detection experiments allowing for directional observables. Due to the motions of the solar system and the Earth relative to the galactic center and the Sun, the dark-matter flux carries a directional preference. We first formulate that...
DUNE aims to measure CP violation in the leptonic sector, observe supernova burst neutrinos, and detect rare processes such as proton decay. To achieve these goals, DUNE will use a highly capable suite of near detectors. The DUNE Near Detector complex for Phase II includes ND-GAr, a magnetized high-pressure gaseous-argon TPC (HPgTPC) surrounded by a calorimeter. Due to the low detection...
Optical and microwave readout of mechanical objects can be used to continuously detect the full 3d momentum vector of the object's center-of-mass. This can be done with target masses ranging from single ions to kilogram-scale objects. Increasingly, the limiting noise in these systems is determined by the quantum mechanical noise in the readout itself (the "standard quantum limit")....
