Investigation and Simulation of Gamma-Neutron Shielding for Nuclear- Pumped Lasers

Mehrdad Shamsinasab; Mansour Asgari; Mahdi Eshghi

Volume 5, Issue 1 , January 2024, Pages 41-47


  Nuclear-pumped lasers (NPL) are lasers that excite the active laser environment caused by nuclear reaction. Such lasers need ionizing radiation shielding for mixed neutron and gamma fields. In this work, a shielding system for NPL was designed which using 10B(n,α)7Li. In this simulation, we have ...  Read More
