The Hefei Advanced Light Facility(HALF)proposed by the National Synchrotron Radiation Laboratory(NSRL)is a diffraction-limited storage ring(DLSR),which plans to use a full energy linac as the injector.To ensure injection efficiency,the injection beam needs to have low emittance.Therefore,a photocathode radio frequency(RF)gun was developed in the HALF R&D project.The gun is designed to deliver high-quality electron bunches with a typically 0.5 nC charge and~4.5 MeV energy with low emittance.The initial system commission with an electron beam was completed at the end of 2020,and a stable 1.2–1.4 mm.mrad emittance with a bunch charge of 500 pC was demonstrated.In this paper,we report the experimental results and experience obtained during the commission,including the RF gun,drive laser system,and beam diagnostics.

Design and offline testing of a resonant stripline beam position monitor for the IRFEL project at NSRL

Nuclear Science and Techniques 2020年第7期31卷 76-84页

作者： Xiao-Yu Liu fang-fang wu Tian-Yu Zhou Ping Lu Bao-Gen Sun National Synchrotron Radiation Laboratory University of Science and Technology of ChinaHefei 230029China

A 476 MHz resonant stripline beam position monitor(BPM)is planned to be installed in an infrared free electron laser machine at National Synchrotron Radiation Laboratory.This type of BPM was developed based on a standard stripline BPM by moving the coupling feedthrough closer to the short end downstream,which introduces a resonance and therefore a capability for higher resolution compared with broadband BPMs.The design and offline measurement results of the prototype are shown in this paper.The design goal is the optimization of the central frequencies and corresponding quality factors of the three intrinsic transverse electromagnetic modes to roughly476 MHz and 30,respectively,the fulfillment of which is demonstrated by a transmission parameter test via a network analyzer.Induced voltage signal modeling and an estimation of the position resolution of the designed BPM are shown in detail.Furthermore,a calibration test of the prototype using the stretched wire method is presented,including a description of the test stand and the evaluation of position sensitivities.

Zoological Research 2020年第4期41卷 381-394页

作者： Qing-Bo Lu Jian-Fei Sun Qu-Yang Yang Wen-Wen Cai Meng-Qin Xia fang-fang wu Ning Gu Zhi-Jun Zhang Department of Neurology Affiliated Zhongda HospitalSchool of MedicineInstitution of NeuropsychiatrySoutheast UniversityNanjingJiangsu 210009China State Key Laboratory of Bioelectronics Jiangsu Key Laboratory of Biomaterials and DevicesSchool of Biological Science and Medical EngineeringSoutheast UniversityNanjingJiangsu 210009China

Magnetic brain stimulation has greatly contributed to the advancement of neuroscience.However,challenges remain in the power of penetration and precision of magnetic stimulation,especially in small animals.Here,a novel combined magnetic stimulation system(c-MSS)was established for brain stimulation in mice.The c-MSS uses a mild magnetic pulse sequence and injection of superparamagnetic iron oxide(SPIO)nanodrugs to elevate local cortical susceptibility.After imaging of the SPIO nanoparticles in the left prelimbic(Pr L)cortex in mice,we determined their safety and physical characteristics.Depressive-like behavior was established in mice using a chronic unpredictable mild stress(CUMS)model.SPIO nanodrugs were then delivered precisely to the left Pr L cortex using in situ injection.A 0.1 T magnetic field(adjustable frequency)was used for magnetic stimulation(5 min/session,two sessions daily).Biomarkers representing therapeutic effects were measured before and after c-MSS intervention.Results showed that c-MSS rapidly improved depressive-like symptoms in CUMS mice after stimulation with a 10 Hz field for 5 d,combined with increased brainderived neurotrophic factor(BDNF)and inactivation of hypothalamic-pituitary-adrenal(HPA)axis function,which enhanced neuronal activity due to SPIO nanoparticle-mediated effects.The c-MSS was safe and effective,representing a novel approach in the selective stimulation of arbitrary cortical targets in small animals,playing a bioelectric role in neural circuit regulation,including antidepressant effects in CUMS mice.This expands the potential applications of magnetic stimulation and progresses brain research towards clinical application.

Nuclear Science and Techniques 2021年第1期32卷 1-9页

作者： Yun-Kun Zhao Bao-Gen Sun Ji-Gang Wang fang-fang wu Ping Lu Tian-Yu Zhou San-Shuang Jin National Synchrotron Radiation Laboratory University of Science and Technology of ChinaHefei 230029China

A radiofrequency(RF)phase modulation method is applied to the Hefei Light Source II storage ring to deeply investigate its longitudinal beam characteristics and improve the beam lifetime.A theoretical analytical model and corresponding experimental measurements of single bunch length and island phenomena are examined.From a series of online machine experiments,we demonstrate that the suitable phase modulation amplitude is 0.02 rad,corresponding to an optimum modulation frequency ranging from 19.6 to 20.7 kHz of the RF system.Furthermore,the overall beam lifetime can be increased by a factor of 2.38 as a result of the beam dilution effect.

Aqueous zinc-ion batteries,especially Zn-Mn02 battery,have attracted intensive attention owing to their unique features of high capacity,environmental friendliness,and safety.However,the problem of Mn dissolution hinders the development of zinc-ion batteries with long-term usage and high-rate performance.In this work,a novel preparation method for the polyaniline(PANI)-coated composite aerogel of Mn02 and rGO(MnO2/rGO/PANI)electrode is reported.The obtained composite possesses high electrical conductivity,and also effectively suppresses the dissolution of Mn.The fabricated Mn02/rGO/PANI//Zn battery exhibits a high capacity of 241.1 mAh·g^-1 at 0.1 A·g^-1,and an excellent capacity retention of 82.7%after 600 charge/discharge cycles.In addition,the rapid diffusion coefficient of the Mn02/rGO/PANI electrode was further examined by galvanostatic intermittent titration technique.This work provides new insights into the development of high-performance Zn-Mn02 battery with a better understanding of its diffusion kinetics.
