"Importance, Mechanism and Application of Inertial Electrostatic Confinement Fusion (IECF) Device and Designing an Optimum Shield for It"
While the majority of fusion energy research is focused on magnetic confinement fusion, there are several alternative confinement methods aimed at the development of smaller and less expensive reactors one of which is inertial electrostatic confinement fusion (IECF). One of the most important characteristics of the IEC device is performing of advanced fusion reactions without radioactive products. But, in comparison to other fusion devices, IECF delivers less output energy and therefore, researchers concentrate on developing this device for a number of near-term applications in the areas such as Neutron Radiography (NR), Prompt-gamma neutron activation analysis (PGNAA), Boron neutron capture therapy (BNCT), detection of illicit drugs and explosive materials, and space craft propulsion. Therefore, despite some restrictions, there are many interests in IEC devices because of their spread applications. Anyway, due to the existence of radiation hazards in each of these applications, it will be inevitable to design a suitable shield for this device based on simulation.
"Calculation of nuclear level density using statistical partition function method"
Nuclear level density (NLD) is a challenging and determinant statistical quantity for the study of nuclear many-body systems and the processes involved in them. It can be said that all the thermodynamic and statistical quantities of a nucleus are obtained from NLD. This quantity is also included in the statistical mechanisms of nuclear reactions as an important input component in many fields of pure and applied nuclear physics. For this reason, it has been studied significantly over the past years and extensive efforts have been made both experimentally and theoretically to determine it accurately. The behavior and dependences of NLD is completely related to the methods and models considered for the nucleus. In this work, a fully recursive microscopic approach based on the partition function method was used in order to accurately determine the NLD for 58Ni.
