Development Of Nuclear Electronics Experiment Platform

It is foreseeable that China nuclear power industry will blow in a broad space in the dual needs of domestic construction and overseas export promotion. As a result, the demand for expert in nuclear electronics has reached a new height. Nuclear Electronics is a practical subject, and all theory courses must be closely matched with the experimental course. We have to pay enough attention to cultivate students' experimental ability in order to have a good grasp of Nuclear Electronics methods and techniques. In turn, we can train better students for the research field of nuclear science and technology. In the field of experimental teaching of nuclear science and technology, University of Science &Technology China has its' natural advantage. We not only have 50 years of accumulation of experience in nuclear and particle physics experiment, but also have a complete curriculum system. In addition to the two opened experimental courses, "nuclear and particle physics basic experiment" and "nuclear and particle physics experiment", we also set the course of "nuclear electronics experiment". It is a basic compulsory course for the major of modern physics department, which can also elected by students from other department and has totaling 60 hours.Nuclear electronics experiment aims to enhance students' understanding of the basic theory, the characteristics of nuclear electronics , and enable students to understand the basic nuclear electronic instruments and grasp the ability to master the correct selection,combination and use of nuclear electronic instrument by experimental training. The experiments include: Basic nuclear electronic instruments, Transmission line, Fast Amplifier, Time Amplitude Conversion, Analog Digital Conversion, Multi-channel Pulse Amplitude Measurement, etc.However, due to outdated equipment, outdated technology, serious damage, and high maintenance cost, the existing experimental system cannot reflect the characteristics of modern nuclear science experiment in the experimental apparatus, experimental methods,experimental management and the goal of training students any more. Only by constantly tracking the new technology in the field of nuclear science and improving the level of experimental teaching, can we meet the needs of the development of nuclear science and needs of talents.In this paper, we design a reconfigurable experimental platform based on the digital technology and the reconfigurable hardware technology developed in recent years. The whole experiment platform includes hardware circuits, function algorithm, interactive software and experiment teaching system. Through the choice of the experimental function and the configuration of the hardware and software, different experimental system can be made up, and then students can complete the whole experiment process on the platform.The features of our design are:1) The introduction of the concept of reconfigurable design in experimental teaching platform. Through the differential configuration of hardware and software, a different experimental platform will be made up, and students can complete different experiments, which facilitate the development of experimental platform.2) We use the latest digital technology, and digital multi-channel pulse amplitude measurement and digital filter are introduced in the teaching experiment.3) The integration of teaching resources, which facilitates students' experiment and teaching management. Students can complete all the experiments required in the course of nuclear electronics on the same platform. For each experiment, students can complete the preparation the experiment on the experimental platform, make the choice of the experiment, the configuration of the parameters, the observation of the experimental process, the processing of experimental data, the completion of the experimental report, and the submission of the experiment.4) We give students enough independent space. According to the requirements of the experiment, the students can configure the experiment system on their own,which is beneficial to the cultivation of students' understanding and innovation ability.5) The cost of teaching is greatly reduced. The use of an experimental platform to complete different experiments greatly reduce the types and number of instruments used, the cost of construction and maintenance costs of the experimental platform. Construction cost is expected to be 1/5 of the original platform, and the maintenance cost is only 1/10 of the original experimental platform.
