Measurement of fusion neutron yields in laser–cluster fusion experiments using binomial statistics

Nuclear Fusion
Accurate neutron-yield measurement is essential for fusion plasma diagnostics. In laser-driven fusion experiments, short-pulse quasi-monoenergetic neutrons can overlap within a narrow time-of-flight (TOF) window, leading to an underestimation of the ...

Helium effect on temperature-displacement rate equivalence in radiation-induced swelling of iron: A study by improved stochastic cluster dynamics

Nuclear Materials and Energy
In nuclear energy systems, understanding material behavior (e.g., swelling) under irradiation is critical for ensuring long-term stability and safety. While direct neutron irradiation experiments pose significant challenges, ion irradiation serves as an ...

Core Optimization for Extending the Graphite Irradiation Lifespan in a Small Modular Thorium-Based Molten Salt Reactor

Journal of Nuclear Engineering
The lifespan of core graphite under neutron irradiation in a commercial molten salt reactor (MSR) has an important influence on its economy. Flattening the fast neutron flux (≥0.05 MeV) distribution in the core is the main method to extend the graphite ...

Cooling rates of neutron stars and the young neutron star in the Cassiopeia A supernova remnant

, 2010
We explore the thermal state of the neutron star in the Cassiopeia A supernova remnant using the recent result of Ho & Heinke that the thermal radiation of this star is well described by a carbon atmosphere model and the emission comes from the ...

Ethane as a Neutron Moderator at Cryogenic Temperatures

EPJ Web of Conferences
The study’s objective is to examine the neutron temperature response, using liquid and solid ethane at various cryogenic temperatures to evaluate the effectiveness of ethane as a cold neutron moderator in compact moderator systems. The experimental measurements were carried out at temperatures of 170 K, 135 K, 100 K, 70 K, 50 K, 25 K, 15 K, and 10 K ...
