| 1 | 4-14 Production of Projectile and Target K-vacancy in Near-symmetric Collisions by 60100 MeV Cu9+ Ions with Thin Zn Target显示文摘The study on ion-solid collisions has important significances not only for fundamental researches but also for technical applications, like ion-beam modification and analysis of surfaces[1]. So far, K-shell ionization has beenmost widely studied for large range of projectile number and incident energy[2;3]. However, even today, a complete theory that can predict K-shell vacancy production for all collision systems in different velocities is still lacking, especially at an intermediate energy. | Guo Yipan Yang Zhihu Du Shubin Chang Hongwei Xia Qingliang Xu Qiumei | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |
| 2 | 4-20 Light Emission from Sputtered Aluminum Atoms and Ions Produced by Kr13+ Ion Bombardment显示文摘When solid surface is bombarded by energetic projectile ions, a fraction of the sputtered particles leaves the surface in electronically excited states. The optical emission in front of the target surface is due to the radiative decay of these sputtered particles[1;2]. The optical emission identifies the target by measurement of wavelength. | Xu Qiumei Guo Yipan | 2015 | IMP & HIRFL Annual Report2015，，1： | 0 |

| 5 | 3-13 Guiding of Electron Beams by Macro-insulating Units显示文摘In our previous work[1],using a pair of grooved SiO2 parallel plates,we had obtained stably guided electron beams without energy loss in the incident energy range of 8002 000 V.The very high-current(up to tens or hundreds of nA/mm2)electron beams were adopted.A 128-strip electrode array with a 128-channel picoammeter system[2],combined with an electrostatic deflector were employed to monitor the transmitted electron beams.To better understanding the guiding processes of electron beams passing through the insulting plates,several grooved parallel plates made by different insulating materials were adopted to study the dependence relative to the guiding beams on the conductivities of these materials.As shown in Fig. | Zhang Mingwu Xue Yingli Li Xin Liu Juliang Yang Bian Wang Wei Guo Yipan Xi Wei Zhu Xiaona Yang Liping Yu Deyang Shao Caojie Cai Xiaohong | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 6 | 3-17 Incident Ion Charge State Dependence of the Visible Light Emission of Xe^q+Ions Bombarding Aluminum显示文摘Slow highly charged ions(HCIs)interaction with the solid also provides information such as electron configuration,multi-interaction,ionization,excitation and charge transfer for the basic research[1??3].What is more,the understanding on the heavy HCI structure and relevant collision processes has a special meaning for inertial confinement fusion(ICF)research.Up to now,many experiments or theories in ion-solid collisions focus on the investigation of secondary electrons,sputtering ion or characteristic X-rays emission by the slow projectile[4]. | Guo Yipan Yang Zhihu Xu Qiumei Ren Jieru Zhao Hongyun Zhao Yongtao | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 7 | 3-22 Visible Light Emission from GaAs Surface Bombarded by Highly Charged Xe^q+Ion显示文摘GaAs is a direct band gap semiconductor,which makes it a very useful material for the manufacture of light emitting diodes and semiconductor lasers.Impact of highly charged ions(HCI)on semiconductor solid surfaces gives rise to visible light emission from excited sputtered atoms.This work measured visible light emission from the monocrystal GaAs(100)surface bombarded by highly charged Xe^q+(6≤q≤23)as a function of charged state of the incident ion.The experiment was carried out at the 320 kV platform for multi-discipline research with HCIs in the Institute of Modern Physics,Chinese Academy of Sciences. | Xu Qiumei Yang Zhihu Chen Yanhong Zhou Xianming Zhao Hongyun Wang Yuyu Cheng Rui Lei Yu Guo Yipan | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 8 | Improvement on Gamma Energy Resolution of Plastic Scintillator by Adding PMMA Light Guider or Chamfer显示文摘Traditional plastic scintillator has respectively low gamma energy resolution.Space radiation detection need the plastic scintillator to keep a relatively better energy resolution for gamma.Thus we did experiments to study how to get it enhanced by adding light guider and chamfer.A 9000 Bq radioactive source 60 Co has been utilized to make the experiment and results came that when keeping other conditions same,the height of poly methyl methacrylate(PMMA)light guider changes from 12 mm to 40 mm and the energy resolutions varied from 72.3%to63.5% respectively.Furthermore,another contrast experiment was made to decide whether plastic scintillator with light guiders or integrated chamfer can get better energy resolution.In conclusion the plastic scintillator with integrated chamfer got 55.0%.Through the study of adding light guider or chamfer to plastic scintillator,the gamma energy resolution has been improved greatly from 72.3%to 55.0%. | Wang Yi Wei Zhiyong Fang Meihua Guo Yipan Yu Junhao | 2018 | Transactions of Nanjing University of Aeronautics and Astronautics2018，35，S1： | 0 |
