  1. 3. The MIGDAL Experiment
    Tim Marley
    12/12/2022, 15:00

    Direct dark matter experiments exploit the Migdal effect to extend their sensitivity to low-mass WIMPs, yet the Migdal effect itself has not yet been observed to occur in nuclear scattering. The MIGDAL experiment aims to directly observe this effect in a low-pressure optical time projection chamber exposed to an intense beam of fast neutrons from DD and DT generators. The experiment uses an...

  2. 19. Commissioning of a hadron blind detector for dielectron measurement in pA reactions at J-PARC

    The J-PARC E16 experiment measures mass spectra of low-mass vector mesons, ρ, ω, and φ, in a nucleus using p + A → ρ/ω/φ + X reactions at the J-PARC high-momentum beamline. The invariant mass of vector mesons is reconstructed with the e+e− decay. The branching ratio of e+e− decay is very low and a thin target of 0.5% radiation length must be used to reduce dielectrons from gamma conversion...

  3. 20. Operation and readout of the CGEM Inner Tracker
    Riccardo Farinelli (Universita e INFN, Ferrara (IT))

    A recently approved ten-year extension of the BESIII experiment (IHEP, Beijing) motivated an upgrade program for both the accelerator and the detector. In particular, the current inner drift chamber is suffering from aging and the proposal is to replace it with a detector based on the cylindrical GEM technology. The CGEM inner tracker consists of three coaxial layers of triple GEM. The tracker...

  4. 21. Performance of the large-area micro-RWELL detectors.
    Lev Shekhtman (Budker Institute of Nuclear Physics (RU))

    Large-area coordinate detectors based on micro-resistive WELL (muRWELL) technology are under development for the CMD-3 detector at the VEPP-2000 collider at Budker INP. The CMD-3 is general purpose detector that is intended to measure parameters of light vector mesons and their excited states with accuracy better than 1% and study dynamics of multihadron production. In order to increase...
