【摘要】 本论文提出了对新型的大学核与粒子物理教学实验平台的概念,针对新型平台所要实现的优点给出了可行性的理论论证和实际的设计方案,并展示了已经完成的设计内容和实际使用情况。实践证明,我们所设计的新型教学实验平台不仅完全满足了传统教学的需要,更进一步增强了学生对核与粒子物理实验的理解,使得我校的实验教学水平将可以走上更高的台阶,对核物理学科的人才培养具有重要的意义。本文的工作主要有以下几个方面：(1)对传统的核与粒子物理教学实验平台进行了深入的研究,重点着眼于对其结构组成、仪器功能和特点的分析,并结合中科大所开设的具体的实验课程内容以及教学经验对实验体系进行了研究和分析。(2)在实验平台的设计中大胆引入了可重构方案,成功完成了一套功能全面,性能优异的实验平台系统。平台的硬件部分充分利用了FPGA动态可重构性的优势,实现了通用化的数据采集和处理功能。新型平台在设计中实现了核实验仪器功能模块化,使用方便,扩展性强,易于开发新的实验。(3)采用LabWindows/CVI开发了以虚拟仪器为核心的软件平台。该软件平台圆满的实现了传统仪器设备的功能,而更加简洁易懂,易于操作。对实验教学起到了很好的推动作用。(4)实验平台的功能设计完全达到了预期效果,不但满足了传统的核物理实验仪器库功能上的需求,在性能上也已经达到甚至超过了传统实验仪器的性能指标。(5)对实验平台在教学中带来的进步和重要意义进行了深入的研究,提出了一些有建设性的意见,为今后的进一步改进和创新拓展了思路。目前,新型教学实验平台己全面覆盖中国科学技术大学“核与粒子物理实验”的基础实验部分,并已在部分专业实验中得到应用。通过一段时间的实验教学,学生们对新型平台系统普遍反映良好,其使用方便、性能稳定,安全可靠的特点获得了师生们的一致认可。在未来的发展中,我们将对平台的功能进行完善并逐步推广到核物理实验体系中的其他实验当中。本论文的主要特色在于：(1)对传统的实验平台体系进行了大幅度的改进,用可重构的模块化硬件体系取代了传统的核电子学仪器库,将目前最新的核电子技术和理念引入到了实验教学当中。新型实验平台的功能完善,使用灵活,并能够针对不同实验进行调整和改进。(2)使用新型实验教学平台进行学习,学生不但能顺利完成实验大纲所要求全部内容,还可以自主的对实验方案进行改进。我们会鼓励学生对实验内容进行探索,并自己发挥对实验方案和平台配置进行改进。(3)新型教学实验平台的设备相比传统系统进行了极大的精简、便于维护,同时对于想要建设相关核物理实验体系的院校来说,其建设周期大幅缩短,投入成本大大降低,是非常理想的选择。更多还原

【Abstract】 This paper presents a new concept of college teaching platform for nuclear and particle physics experiment, a new platform for the advantages to be achieved given the theoretical feasibility demonstration and practical design, and shows the design has been completed and the actual use of the content situation. Practice has proved that we have designed a new type of teaching experiment platform not only to fully meet the needs of traditional teaching, and further enhance the student for nuclear and particle physics experiments to understand, so my school experimental teaching level will be taken to a higher level, for nuclear physics personnel training has an important significance.This work mainly in the following aspects:(1) The traditional nuclear and particle physics teaching experiment platform conducted in-depth research, a focus on the composition of its structure, the instrument functions and features of the analysis, combined with USTC opened by specific experimental curriculum content and teaching experience in the experimental system was research and analysis.(2) In the experimental platform introduces a bold design reconfigurable solutions, the successful completion of a full-featured, high-performance test platform. The hardware part of the platform takes full advantage of FPGA dynamic reconfigurability advantages, to achieve a universal data acquisition and processing functions. The new platform is implemented in the design of nuclear test instrument function modular, easy to use, extensible, easy to develop a new experiment.(3) Using Lab Windows/CVI virtual instrument developed in the core of the software platform. The software platform for successful implementation of the traditional instruments and equipment features, find more easy to read, easy to operate. Experimental teaching has been much promoted.(4) Experimental platform functional design fully meet the expected results, not only to meet the traditional nuclear physics laboratory instruments library functional requirements, the performance has met or exceeded the traditional experimental equipment performance indicators.(5) Experimental platform to bring progress in the teaching and importance of in-depth study and put forward some constructive suggestions for future improvements and innovations to further expand the idea.Currently, the new teaching experiment platform has comprehensive coverage University of Science and Technology of China of the "nuclear and particle physics experiments " based experimental part, and has been part of the professional experiment in the applications. Through a period of experimental teaching, students reflect on the new platform system generally good, and its easy to use, stable performance, safe and reliable access to the teachers and students unanimously approved. In the future, we will improve the function of the platform and gradually extended to the nuclear physics experimental system in which other experiments.In this thesis, the main features are:(1) The traditional system for experimental platform has been a significant improvement, with a reconfigurable modular hardware system replaces the traditional nuclear electronics instrumentation library, will present the latest technologies and nuclear electronics concept to the experimental teaching them New experimental platform functional, flexible, and able to be adjusted for different experiments and improvements.(2) The use of new experimental teaching platform, students can not only successfully completed the required experimental outline the entire contents, you can also customize the experimental program improvement. We will encourage students to experiment content to explore, experiment and play their own programs and platform configuration improvements.(3) New teaching experiment platform devices compared to traditional systems greatly streamlined, easy to maintain, and who want to build nuclear physics experiments related to system institutions, its construction period shortened significantly reduce input costs, is an ideal selection.更多还原
