This paper experimentally demonstrates that free electrons transfer momentum to planar samples during optical-mode excitation, a phenomenon that alters the apparent dispersion relation and can result in the sample receiving momentum opposite to the electron beam direction.
This paper presents a detector-level assessment of Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) observability across various target nuclei using Geant4 simulations, demonstrating how realistic detector effects like energy thresholds and resolution significantly shape measurable recoil spectra and highlighting the critical role of detector response in optimizing future low-threshold experiments.
This paper demonstrates single-photon counting capabilities of superconducting Microwave Kinetic Inductance Detectors across the 3.8 to 25 m mid-infrared range, achieving high spectral resolving powers and ultra-low dark count rates with membrane-based designs that significantly outperform solid-substrate counterparts.
This paper proposes a compact, scanning-geometry scheme for hard X-ray phase-contrast imaging that utilizes a two-block crystal system with a phase shifter to achieve Zernike-type contrast without conventional focusing optics, supported by numerical simulations of image formation.
This paper presents a fast, data-driven simulation method for the MALTA2 depleted monolithic active pixel sensor that accurately reproduces measured in-pixel efficiency without requiring proprietary process details, offering a computationally efficient alternative to TCAD simulations for optimizing future high-rate particle tracking and calorimetry designs.
This paper presents the design, fabrication, and successful high-altitude balloon testing of CubeSounder, a low SWaP-C 180 GHz radiometer utilizing passive waveguide filter banks for atmospheric water vapor sensing.
This paper presents a scalable, FPGA-based Time-to-Digital Converter (TDC) for Quantum Key Distribution that achieves a 27 ps residual jitter and maintains steady performance through a continuous, single-photon detection-based calibration method that eliminates data loss and operates reliably across a wide temperature range.
Researchers at the Saha Institute of Nuclear Physics designed, fabricated, and validated a Micromegas-based active-target Time Projection Chamber (SAT-TPC) for nuclear astrophysics, demonstrating its capability to accurately reconstruct particle trajectories and energy in various gas mixtures through experimental testing and hydrodynamic simulations.
This paper summarizes the outcomes of the June 2023 MiND workshop, which brought together experts to identify priority nuclear data needs and establish a roadmap for improving the accuracy of microcalorimetry-based non-destructive assay for nuclear safeguards.
This paper reports on the successful implementation and performance of a new fission-fragment detection system within the NECTAR experiment at the ESR storage ring, which enabled the first simultaneous detection of -decay residues, multi-neutron-emission residues, and fission fragments during surrogate neutron-capture studies using a stored U beam and a deuterium target.
