Direct measurement of neutrons induced in lead by cosmic muons at a shallow underground site

, 2018
Neutron production in lead by cosmic muons has been studied with a Gadolinium doped liquid scintillator detector. The detector was installed next to the Muon-Induced Neutron Indirect Detection EXperiment (MINIDEX), permanently located in the T\"ubingen ...

GEANT4 parameter tuning using Professor

Journal of Instrumentation, 2020
The Geant4 toolkit is used extensively in high energy physics to simulate the passage of particles through matter and to predict effects such as detector efficiencies and smearing. Geant4 uses many underlying models to predict particle interaction kinematics, and uncertainty in these models leads to uncertainty in high energy physics measurements.

Direct Growth of Transparent Boron Nitride Neutron Shielding Layer for Space Window

Advanced Science, EarlyView.
Direct growth of sp2‐sp3 hybridized BN (HBN) on quartz, enabled by an h‐BN buffer, produces transparent and stable films up to 80 µm thick with high transmittance and strong neutron shielding, making HBN a promising candidate for space windows in long‐term lunar missions.

Photonuclear Population of 229m,gTh in Th‐Doped Crystals Toward Nuclear Clock Development

Advanced Science, EarlyView.
This study demonstrates a novel photonuclear approach for producing the nuclear clock isomer 229mTh in thorium‐doped crystals, overcoming current supply limitations. Through cross‐section calculations and Monte Carlo simulations, we identify optimal crystal materials and irradiation conditions, achieving high signal‐to‐noise ratios.

Response simulation and primary vertex reconstruction in the SPD NICA straw tracker

Вестник Самарского университета: Естественнонаучная серия
In this work we investigate the temporal structure of the events in the spin physics detector (SPD) straw tracker at the JINR NICA. Using the Geant4 toolkit we simulate the response of the straw layers sensitive elements in the triggerfree regime of SPD.
