| 1 | 通过中微子散散实验提取原子核形状因子显示文摘This year we continued to study experiments that can be performed using neutrinos produced via Decay At Rest(DAR)at spallation sources.In 2017 the COHERENT collaboration was able to measure for the first time Coherent Elastic Neutrino Nucleus Scattering(CENNS)[1]:neutrinos are produced at the Spallation Neutruon Source(SNS)via Pion Decay At Rest(πDAR).The study on CENNS brings us to a new precision era:first of all,any deviation from the Standard Model prediction can be a sign of new physics;moreover,neutrino-nucleus interactions are crucial in the understating of core collapse supernovae,and information on the CENNS cross section can be useful for the next generation dark matter detectors,since they are rapidly approaching to the intrinsic neutrino background floor. | E.Ciuffoli J.Evslin Q.Fu H.Mohammed J.Tang | 2018 | IMP & HIRFL Annual Report2018，，1： | 0 |
| 2 | Kaoline-based catalyst for a high stability desulfurization of sour heavy naphtha in a three-phase oscillatory baffled reactor显示文摘To meet the rapidly increasing demand for energy and the dramatic depletion of conventional crude oil,it is imperative to utilize sour naphtha.With no coke being produced,oxidative desulfurization(ODS)of naphtha lowers its sulfur content and average molecular weight.In this article,we outline a method for heavy naphtha non-extractive ODS using a very stable catalyst.The technique involves the use of a solid catalyst with oxygen gas as the oxidant.This necessitated relatively high mixing intensities;hence a three-phase Oscillatory Baffled Reactor(OBR)was used.The catalyst was based on the zeolite ZSM-5,prepared from natural kaolin by a series of delamination and activation steps and impregnated with Fe.A TiO2 nanolayer was applied,using the sol-gel method,to prevent rapid deactivation.The reactor performance was evaluated to minimize the sulfur content in the naphtha fuel.Due to the protective coating,the sulfur conversion stabilized at 90%.The results of this work establish the use of natural clay-based catalysts in a continuous,three-phase ODS,particularly with regard to proving long-term stability.It also showed that modest ODS can be achieved using an environmentally friendly oxidant,at mild operating conditions,whilst maintaining stability. | Hassan M.Hmood Saba A.Gheni Safaa M.R.Ahmed Mudheher M.Ali Hamid Yonis Saleh Mohammed H.Mohammed Awad E.Mohammed Marwan A.Mahomood Hiba R.Mohammed Ahmed A.Hassan Adam Harvey | 2024 | Particuology2024，84，1： | 0 |
| 3 | IsoDAR中微子物理研究显示文摘Several experiments intend to use neutrinos produced via Isotope Decay At Rest(IsoDAR)to search for signs of the presence of sterile neutrinos.In most IsoDAR experiments spallation neutrons are absorbed in a ^(7)Li sleeve(converter),creating ^(8)Li,that will decay emitting νe.Often IsoDAR proposals plan to use existing detectors or accelerators,to reduce the cost of the experiment.In particular,it has been proposed to use as a neutron source the high-intensity proton accelerators that will be built as a part of the China Accelerator Driven System(C-ADS)program[1]. | E.Ciuffoli H.Mohammed J.Evslin F.Y.Zhao M.Deliyergiyev | 2017 | IMP & HIRFL Annual Report2017，，1： | 0 |
