چکیده
Passive radiation shielding alone is insufficient for protecting astronauts from galactic cosmic ray exposure. Active shields, utilizing electromagnetic fields to deflect heavy charged ions in space, could be used supplement conventional passive shielding. Due experimental limitations, simulation capability crucial designing effective active shields. The purpose of this work validate the Shielding Particle Pusher (ASPP) code, characterize efficacy, using beamline measurements conducted at Brookhaven National Laboratory. Emphasis placed on (1) comparing efficacy as a function scaled dimensionless parameter among various electric dipole sphere sizes and center-to-center distances, (2) rotation angle voltage applied each varied independently, (3) observed simulations broaden validation domain ASPP. Simulated measured data are shown agree within factor 1.10 average. results demonstrate that scaling parameters characteristic shield incident can create laws range ion species relevant exposure energies.

Introduction: In radiation therapy, in order to double-check the dosimetric results of the main treatment planning system (TPS), a distinct TPS, with few capacitances in terms of contouring and a variety of dose calculation algorithms is used. This system has the capability to double check the planification and the accurate prediction of dose distribution in order to be ensured...
متن کاملExperimental Validation of Particle - Based Discrete Element Methods
As a consequence of its particulate nature, soil exhibits a highly complex response to applied loads and deformations. Traditionally, geotechnical engineers have coupled continuum numerical analysis tools (such as the finite element method) with complex constitutive models to analyze soil response. This approach does not explicitly consider the particle-scale interactions underlying the macro-s...
