This study utilizes GRAS/Geant4 simulations to characterize background count rates in low Earth orbiting Cherenkov detectors, demonstrating that while coincidence techniques effectively mitigate trapped particle interference to enable detailed spectral analysis of Ground-Level Enhancements, significant background rates persist in the South Atlantic Anomaly.
This paper characterizes delayed electron backgrounds in the LUX-ZEPLIN detector and demonstrates that spontaneous grid electron emission can be efficiently rejected using coincident photon tagging, thereby enhancing the experiment's sensitivity to low-energy dark matter signals.
This study characterizes thin optical filters for hybrid dual-readout calorimeters, demonstrating that while interference filters are unsuitable due to angle-dependent transmittance, specific absorptive long-pass filters effectively block over 99% of scintillation light from PWO crystals to enable high-purity Cherenkov light readout.
This paper presents a quantitative validation of Fluka simulations against experimental data from a pulsed neutron source test at CERN's DUNE ColdBox facility, demonstrating strong agreement in photoelectron counts and time constants for a small vertical drift LArTPC while identifying systematic effects for future large-scale detectors.
This study demonstrates that 4H-SiC PIN diodes exhibit exceptional radiation tolerance up to 2 MGy of X-ray irradiation, maintaining ultralow leakage currents, high charge collection efficiency, and stable picosecond-level time resolution, thereby confirming their suitability for extreme radiation environments in high-energy physics and space applications.
This paper presents the design and implementation of a high-density, sub-nanosecond timing system for a C-band photocathode electron gun test platform, featuring a compact 6U VME architecture with 80 (expandable to 160) synchronized channels that achieves ultra-low jitter performance and reliable routine operation at the Southern Advanced Photon Source.
This paper demonstrates that PICOSEC Micromegas detectors equipped with high-granularity readout pads can achieve a spatial resolution of approximately 0.5 mm while maintaining a time resolution better than 20 ps, enabling their simultaneous use as precise timing and moderate-resolution tracking detectors.
This paper presents a minimal-component, transformer-free full-duplex digital link over a single coaxial cable that achieves reliable 100 MHz bidirectional transmission with sub-nanosecond jitter by utilizing a passive resistive hybrid and standard logic components, making it ideal for space-constrained laboratory instrumentation.
This paper introduces XCOM, a high-performance network designed to synchronize QICK control boards with sub-100 ps precision and enable deterministic all-to-all communication with latency under 185 ns, thereby addressing the critical scaling challenges of large-scale superconducting and spin qubit testbeds.
This paper presents the updated MIDNA ASIC, a 65 nm CMOS skipper-CCD readout chip featuring an integrated cryogenic voltage reference and improved channel isolation, which achieves sub-electron noise performance of 0.11 erms at 140 K through analog pile-up averaging.
