Contribution of cosmic alphas to generation of albedo neutrons and gammas in lunar regolith: A computational study based on GEANT4 simulations
Harshala Gaonkar, A. Ilker Topuz
The lunar surface is constantly and directly exposed to Galactic Cosmic Rays (GCRs) due to the lack of the atmosphere and the magnetic field around it. The high-energetic alpha par…
Unveiling neutron and gamma spectrum at Martian surface in presence and absence of hydrogen: A computational study based on GEANT4 simulations
A. Ilker Topuz
Motivated by the interactions of the GCR protons with the Martian atmosphere and regolith in the absence and presence of hydrogen, a series of GEANT4 simulations are employed in th…
Neutronic Analysis of a Nuclear-Chicago NH3 Neutron Howitzer
Ahmet Ilker Topuz, Iskender Atilla Reyhancan
Neutron howitzers are the irradiation instruments, generally used for the chemical analysis in the research laboratories, where the neutron sources are encapsulated within a modera…
3D Surface Radiation Dosimetry of a Nuclear-Chicago NH3 Neutron Howitzer
Ahmet Ilker Topuz, Iskender Atilla Reyhancan
The tracking of radiation dose is a fundamental concept for the safe operation of nuclear instruments, and this concept is a multi-task challenge in the case of neutron sources sin…
