Along with the science development, many disciplines all need under certain extreme condition (for example extremely high temperature, enormous pressure, extremely high electric field and magnetic field and so on) conduct the research to the material physical property. Shanghai Synchrotron Radiation Facility provides a good experimental workbench for these kinds of scientific research. It not only supports basic research and applied research, but also to advance in technology, industrial development and productive forces enhancement direct promoter action.Because this test installation is special to the temperature and the precision control request, therefore, this article through massive literature reading, the domestic and foreign material retrieval as well as the experiment debugs the data acquisition, progresses in the scope in the project which permits, has made a more thorough analysis and the research to this large-scale experiment facility constant temperature aqueous system.First, through the direct participation partial facility design and the debugging, from the structure, the experimental principle, the temperature request, the scientific research application and the social significance and so on several aspects begins, the author conducts exhaustive and thorough investigation and study on the Shanghai Synchrotron Radiation large-scale scientific experiment instrument.Next, from the system constitution, the temperature and the precision request and so on several aspects, the author has carried on a more detailed analysis and the research to the experimental facility constant temperature cooling aqueous system. At the same time, unifies a series of experiments which obtains to debug the data, the author carries on certain analysis and comparison on two different kinds of constant temperature control plan. One is using heaters to heat up the temperature of the water to the require point, the other is to mix two lines of water with different temperature to acquire the water temperature needed. And then, she also summarized both respective good and bad points and the suitable situation.Third, the selection linear accelerator system is the object of study, in to practices the experiment and the debugging data which in the investigation and study obtains carries on the reorganization and in the analysis foundation, to experiments separately coldly hotly exchanges the water plan which the advanced research stage uses, as well as in the actual project uses the electric heating plan-these two kind of constant temperature cooling aqueous system respective debugging movement situation has carried on the analysis and the research. And in this foundation, the author separately summarized two kinds of constant temperature way existence main question and the insufficiency.Fourth, with the aid of the finite element analysis software, this paper conducts the research to the accelerating tube internal temperature distribution situation as well as the change tendency, In heat transfer theory principle foundation, carried on certain heat transfer to the simple root accelerating tube to study and to analyze, through inspected the accelerating tube in the heat transfer in steady state situation, in the tube the temperature distribution and the change tendency, understood and grasping accelerating tube crosswise and longitudinal two aspect thermal transmission as well as temperature distribution situation, and further promulgated the constant temperature system the temperature fluctuation the influence which produced to the accelerating tube body, thus for well the control and the adjustment entire constant temperature aqueous system constant temperature and the precision, guaranteed the entire particle accelerator test installation the normal work and the movement provides the theoretical analysis and the basis.
