“…[ 286 ] The maximum |Δ s m | reaches 15.0 J kg −1 K −1 for Δµ 0 H of 5 T in the former. Interestingly, rare‐earth‐based HEAs in the form of microwires [ 287,288 ] and ribbons [ 289–293 ] fabricated by melt‐extraction techniques show a better magnetocaloric performance (larger Δ s m or wider temperature span) than their bulk counterparts. For instance, a large |Δ s m | of 15.73 J kg −1 K −1 is obtained in Er 20 Tm 20 Ho 20 Cu 20 Co 20 amorphous ribbons for Δµ 0 H = 5 T, which is much larger than typical rare‐earth‐based BMGs.…”

Solid‐state caloric effects as intrinsic thermal responses to different physical external stimuli (magnetic‐, uniaxial stress‐, pressure‐, and electric‐fields) can achieve a higher energy efficiency compared with traditional gas compression techniques. Among these effects, magnetocaloric energy conversion is regarded as the best available alternative and has been exploited extensively for promising application scenarios in the last decades. This review systematically introduces the magnetocaloric effect and its applications, and summarizes the corresponding representative magnetocaloric materials, as well as important progress in recent years. Specifically, the review focuses on some key understandings of the magnetocaloric effect by utilizing state‐of‐the‐art technical tools such as synchrotron X‐ray, neutron scattering, muon spin spectroscopy, positron annihilation spectroscopy, high magnetic fields, etc., and highlights their importance toward advanced materials design and development. An overview of the basic principles and applications of these advanced techniques on magnetocaloric materials is provided. Finally, the challenges and perspectives on further developments in this field are discussed. Further in‐depth understanding and manufacturing technology advancement combined with fast‐developed artificial intelligence and machine learning are expected to advance the magnetocaloric energy conversion technology closer to real applications.

“…Depleted uranium is widely used in fields such as weapons physics, fusion-fission hybrid reactors and nuclear physics [1][2][3]. When a nuclear explosion occurs, the prompt radiation measurement [4][5][6][7] is an essential diagnostic method. In the design of hybrid-reactor physics, the radiation effects and 238 U nuclear parameters must be taken into account.…”

The prompt γ-ray spectrum from depleted uranium (DU) spherical shells induced by 14 MeV D-T neutrons is measured. Monte Carlo (MC) simulation gives the largest prompt γ flux with the optimal thickness of the DU spherical shells 3–5 cm and the optimal frequency of neutron pulse 1 MHz. The method of time of flight and pulse shape coincidence with energy (DC-TOF) is proposed, and the subtraction of the background γ-rays discussed in detail. The electron recoil spectrum and time spectrum of the prompt γ-rays are obtained based on a 2″×2″ BC501A liquid scintillator detector. The energy spectrum and time spectrum of prompt γ-rays are obtained based on an iterative unfolding method that can remove the influence of γ-rays response matrix and pulsed neutron shape. The measured time spectrum and the calculated results are roughly consistent with each other. Experimental prompt γ-ray spectrum in the 0.4–3 MeV energy region agrees well with MC simulation based on the ENDF/BVI.5 library, and the discrepancies for the integral quantities of γ-rays of energy 0.4–1 MeV and 1–3 MeV are 9.2% and 1.1%, respectively.
