Neutron shielding calculations have complex challenges that require conservative planning in designing shielding to meet radiation protection standards. Formerly, hydrogenous materials such as concrete, water, and polyethylene have been chosen to against neutron radiation. However, in high energy neutron sources, the use of these materials will require a very thick shielding design so that it...

Negative pi-meson therapy has potential as an alternative radiotherapy method because it has a high radiation level, while healthy organs around it receive a low radiation dose. Negative pi-meson-based treatment is suitable for targeting tumours with many vital organs around them, one of which is prostate cancer. This study aims to analyse the dose and time of irradiation of negative pi-meson...

A compact 3 GeV next-generation synchrotron radiation facility, NanoTerasu, is currently constructed at Aobayama New campus of Tohoku University in Miyagi prefecture, Japan. NanoTerasu provides both soft and hard x-rays, and is to be operational from April of 2024 with 10 beamlines; it will have 28 beamlines in the future. The electrons are accelerated up to 3 GeV by LINAC, and injecting into...

In this study, Monte Carlo methods were used to estimate the absorbed-dose energy dependency of 4 widely used optically and thermally stimulated luminescence materials: CaSO4, LiF, BeO, Al2O3. The examined X-ray / photon energy range was 20 keV to 400 MeV. Three well-known general-purpose Monte Carlo codes were used: FLUKA, GEANT4, and PHITS. The results obtained from these completely...

This article involves two main objectives of the BNCT system. The first goal includes optimization of 30 MeV Cyclotron-based Boron Neutron Capture Therapy (BNCT) beam shaping assembly. The second goal is to calculate the neutron flux and dosimetry system of BNCT in the head and neck soft tissue sarcoma. A series of simulations has been carried out using a Particle and Heavy Ion Transport Code...

The Beam-Test Facility (BTF) of the INFN - National Laboratories of Frascati is an extraction and transport line of DAFNE LINAC. It is optimized for the production of electrons and positrons in a wide range of intensity, energy (30 MeV – 750 MeV), beam spot dimensions and divergence, using both primary and secondary beam of the DAFNE LINAC.

The Mu2e experiment, which is currently under construction at the Fermilab Muon Campus, will search for the charged-lepton flavor violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus. The conversion process results in a monochromatic electron with an energy of 104.97 MeV, and observations of a signal would require physics beyond the Standard...

The upgrade of the storage ring of Synchrotron SOLEIL, the French 3rd generation synchrotron light source, to a 4th generation ring, based on multi-bend achromat to achieve a very low emittance electron beam (~80 pm.rad), has entered the TDR phase.
This upgrade will led to the decommissioning of the present storage ring. In France, it is mandatory before the shutdown to submit to the French...

One Best 35p Cyclotron is planned to be assembled and subsequently operated at CGN Mianyang, Sichuan in China. As a previous preparation for the arriving of this commercial accelerator, it is required to perform shielding calculations in order to verify and or improve the current proposed design for the facility — this proposed design is the one suggested by the manufacturer of the machine....

At high-energy electron accelerator facilities, neutron shielding is one of the main considerations in radiation shielding due to the generation of secondary neutrons by the interactions of primary and secondary particles with surrounding materials. Neutrons produced from these interactions will have wide-energy spectrum based on the incident particle energy. Higher part of neutron energy...

In recent years, the development of high-current accelerator-based neutron sources (HiCANS) has gained in interest to propose an alternative to research reactors. In HiCANS high neutron yields are achieved by irradiating metal targets with proton beams with energies in the MeV range bellow the spallation threshold and currents of several tens of milliamps. Based on this concept, the High...

One of the most crucial elements in following reasonable radiation procedures is calibrating and measuring the radiation doses to ensure the process is done correctly. Due to its small size and precise requirements for its dose-measuring equipment, the B3 dosimeter—a radiochromic film made of polyvinyl butyral (PVB) resin mixed with the radiochromic dye (pararosaniline)—is being used more...
