摘要

ZnO:Ga is a promising, high time resolution candidate for use as a fast-ion-loss detector in TJ-II. We compare its ionoluminescence with that of the standard fast-ion-loss detector material, SrGa2S4:Eu (also known as TG-Green), when irradiated by H+ ions with a range of energies E <= 60 keV using a dedicated laboratory setup. It is found that ZnO:Ga is a reasonably good candidate for detecting low energy (E < 60 keV) ions as it has excellent time resolution; however, its sensitivity is about 100 times lower than TG-Green, potentially limiting it to applications with high energy ion loss signals.

Acid response nanochannels of graphene oxide membranes for fast nuclide ions separation

Shuai Wang, Shanshan Liang

Summary: In this study, a pH-responsive graphene oxide (GO) membrane, known as a pGO membrane, was developed for fast and efficient selective separation of Sr2+ nuclide ion from highly acidic radioactive wastewater. The pGO membrane has adjustable and enlarged nanochannels that can effectively block larger and highly charged hydrated Sr2+ nuclide ions while allowing smaller and lowly charged monovalent salt ions to rapidly transport through the membrane.

Development of a compact fast-neutron spectrometer for nuclear emergency response applications

J. F. Perello, T. H. Shin, T. Cutler, K. D. Bartlett, C. Bates, D. Beckman, T. C. Borgwardt, D. Hemsing, D. Mercer, K. Smith

Summary: We have developed a Compact Fast Neutron Spectrometer (CFNS) for passive assay of special nuclear material (SNM) through the observation of fast neutrons. The CFNS determines the neutron energy profile by spectrum unfolding using the Maximum-Likelihood Expectation Maximization method. The results show that the CFNS can be used to distinguish between different neutron emitters and configurations of Pu oxide and metal.

Fast response 4f15d1?4f2 emission and host-to-impurity energy transfer in Pr3+doped Na3LuSi3O9 double salt silicate

Mengjiao Li, Qiufeng Shi, Konstantin V. Ivanovskikh, Jianwei Qiao, Lei Wang, Haijie Guo, Ping Huang, Sviatoslav A. Kiselev, Vladimir A. Pustovarov

Summary: Understanding the energy transfer process between host and impurity is crucial for the development of efficient and fast response scintillator materials. In this study, Pr3+ doped Na3LuSi3O9 double salt silicate was successfully synthesized and comprehensively characterized. The results demonstrate that NLS:Pr3+ has a good potential for fast response scintillator applications due to the efficient energy transfer from host electronic excitations to Pr3+ states.

Antimonene-Modified Screen-Printed Carbon Nanofibers Electrode for Enhanced Electroanalytical Response of Metal Ions

Maria A. Tapia, Clara Perez-Rafols, Filipa M. Oliveira, Rui Gusmao, Nuria Serrano, Zdenek Sofer, Jose Manuel Diaz-Cruz

Summary: A two-dimensional Sb-modified screen-printed carbon nanofibers electrode (2D Sb-exf-SPCNFE) was developed to enhance the determination of Cd(II) and Pb(II) by stripping voltammetry, utilizing the synergistic effect between the two nanomaterials. The surface morphology of the 2D Sb-exf-SPCNFE was analyzed and compared to other modified and bare electrodes. The 2D Sb-exf-SPCNFE exhibited improved analytical parameters and higher sensitivities compared to other sensors, and was successfully applied to detect Cd(II) and Pb(II) traces in a certified estuarine water sample.

Fast neutron response characterization of an EJ-276 plastic scintillator for use as a neutron monitor

Khai D. Ngo, Carlo Cazzaniga, Michela Paoletti, Davide Rigamonti, Maria Kastriotou, Christopher Frost, Marco Tardocchi, Jeff Sykora, Sarah Mann, Benjamin Lutz, Ralf Nolte

Summary: In this study, the neutron response functions, proton light output, and detection efficiency of EJ-276 plastic scintillator were measured using mono-energetic neutron reference fields. The study also investigated the optimization of Pulse Shape Discrimination and demonstrated how to discriminate scattered and spurious neutrons from the mono-energetic beam. The results can be used for monitoring neutron fields and gamma background at the new Neutron Irradiation Laboratory for Electronics facility.

Summary: The performance of two Li-6 enriched elpasolite scintillators, CLYC and CLLB, were studied using mono-energetic fast neutrons. CLYC showed excellent discrimination ability between neutron and gamma rays, while CLLB was only sensitive to slow neutrons. An ANN model effectively discriminated fast neutrons and scattered slow neutrons with an accuracy of 97%. The detection efficiency for fast neutrons ranged from 0.1% to 0.75% within the energy range of 0.9-5.2 MeV.

Fast Neutron Scintillator Screens for Neutron Imaging Using a Layered Polymer-Phosphor Architecture

William Chuirazzi, Aaron Craft, Burkhard Schillinger, Jesus Mendoza, Steven Cool, Adrian Losko

Summary: Fast neutron imaging enables nondestructive examination of dense, large, and highly attenuating samples. However, the lower spatial resolution caused by thicker sensors required to detect fast neutrons is a challenge. This study explores the advantages of a layered polymer-phosphor screen approach in fast neutron imaging. Experimental and simulation results determine the optimal thickness of the screen and the imaging performance is tested using the NECTAR experimental platform. Additionally, distinguishing between fast neutron and gamma-ray signals is identified as a major challenge in fast neutron imaging.

Yue Mou, Yanfei Zhang, Xinru Lin, Meiyun Chen, Yuxiang Xia, Shu Zhu, Chonghui Wei, Xingyu Luo

Summary: Heavy metal pollution, especially copper ions (Cu2+), poses a significant threat to the environment and human health. The conventional detection methods for Cu2+ are inadequate for practical analysis in aquatic environments. In this study, a novel fluorescent DNA aptasensor was developed to detect Cu2+ with fast response, anti-interference properties, and high sensitivity.

Fast synthesis of Hcy-modified Au nanoclusters under microwave-assisted irradiation and their response to Cu (II) ions

Yong Shen, Xin Wang, Yunfei Xia, Ping Li, Yinan Ding, Tian Luan, Kai Song

Summary: In this study, Cu (II) ion was chosen as the analyte due to its importance as a trace element in maintaining human health. Gold nanoclusters (AuNCs) with a mean diameter of about 2 nm were prepared using homocysteine (Hcy) as a reducer and stabilizer. The Hcy-modified AuNCs exhibited red emission that was effectively quenched by Cu (II), showing good selectivity and a quenching mechanism of charge transfer. The Hcy-modified AuNCs offered the advantage of easy and quick synthesis, along with satisfactory sensing performance in terms of selectivity, linear response, and wide working range.

Summary: This article reports on TJ-II stellarator research, including modelling and validation of plasma flow asymmetries, plasma fuelling physics, control and stability of Alfven eigenmodes (AEs), the interplay between turbulence and neoclassical mechanisms, and liquid metal behavior. Experimental validation of neoclassically predicted potential asymmetries impacting the radial electric field has been achieved. Research indicates that turbulence and fluctuations are strongly affected during particle injection processes. Advanced analysis tools show that radial electric fields not only affect turbulence correlation length but also reduce turbulence propagation from the edge to the scrape-off layer.

Summary: This article summarizes the results of L-II transition experiments conducted at JET since the installation of the ITER-like wall, indicating differences in power threshold and density between different plasmas. For helium plasmas, the minimum power threshold density is higher compared to deuterium and hydrogen plasmas.

Power balance analysis at the L-H transition in JET-ILW NBI-heated deuterium plasmas

P. Vincenzi, E. R. Solano, E. Delabie, C. Bourdelle, G. Snoep, A. Baciero, G. Birkenmeier, P. Carvalho, M. Cavedon, M. Chernyshova, J. Citrin, J. M. Fontdecaba, J. C. Hillesheim, A. Huber, C. Maggi, S. Menmuir, F. Parra

Summary: Understanding the physics underlying the L-H transition is crucial for ITER experimental reactor and DEMO. This study focuses on the L-H transitions of JET deuterium plasmas heated by neutral beam injection, using a power balance analysis and integrated transport modeling. The results show a minimum L-H power threshold at a certain plasma density, indicating the presence of density branches and a minimum electron density. The study also compares the results with other heating methods and discusses the role of ion heat flux.
