This tabletop study experimentally validates a proposed kilohertz gravitational-wave detector topology by demonstrating that an L-shaped cavity pumped via a Sagnac-like vortex exhibits a simple Michelson-like response with a transparent input coupler and independent upper/lower pumping paths, thereby confirming theoretical predictions and informing future lock acquisition strategies.
The ALICE ITS3 upgrade replaces the innermost tracking layers with a fully cylindrical, self-supporting silicon vertex detector using 65nm CMOS Monolithic Active Pixel Sensors and wafer-scale stitching to achieve an ultra-low material budget of less than 0.09% X per layer while transitioning to air cooling.
This paper reports the fabrication, conditioning, and comprehensive characterization of locally manufactured Thick-GEM detectors in India, demonstrating their suitability for muography applications through high muon detection efficiency (up to 99.5%) and excellent spatial resolution (30 m).
This paper evaluates the shielding efficiency of water, HDPE, and boron-loaded HDPE for the ALARM neutrino detector, demonstrating through experiments and simulations that a 30-cm thickness of boron-loaded HDPE achieves over 95% shielding against both fast and thermal neutrons.
This paper presents a data-driven fast simulation algorithm for pion showers in the CALICE AHCAL Technological Prototype, developed using kernel density estimators on 2018 test beam data, which achieves excellent agreement with measured observables and includes a method for interpolating showers at arbitrary energies.
This paper introduces Broadband Cryogenic Transient Dielectric Spectroscopy (BCTDS), a novel wafer-level technique that utilizes transient phase dynamics under strong microwave excitation to characterize the frequency-dependent behavior and thermocycling-induced shifts of two-level system (TLS) defects in dielectrics, thereby offering a powerful tool for understanding decoherence sources in superconducting quantum circuits.
This whitepaper proposes the Hyperon-Nucleon Spectrometer (H-NS) at the High-Intensity heavy-ion Accelerator Facility (HIAF) to systematically investigate the unresolved polarization puzzle through high-precision measurements of hyperon and proton spin observables across a wide range of collision energies and systems.
This thesis provides an overview of 4D-STEM ptychography, mathematically explores reconstruction methods like ePIE, WDD, and SSB, and demonstrates their application through simulated MoS₂ data and experimental 4D-STEM recordings.
This paper reports the successful kilogram-scale production and characterization of EJ-299-50, a Li-doped plastic scintillator with pulse-shape discrimination capabilities that exhibits optical properties comparable to liquid scintillators, high neutron capture efficiency, and long-term stability.
This paper establishes a full optical transfer function model for X-ray beam-tracking microscopy and experimentally validates it, demonstrating that the technique achieves a spatial resolution of at least 3 µm—significantly surpassing the aperture size—and formally confirming the anomalously high sharpness of its dark-field channel.
