Research And Implementation Of Data Acquisition And Storage For JUNO Detector Prototype Control System

Neutrinos are the fundamental particles of the material world.Since the cross section of the interaction is vary small,they have a strong penetration properties.People can understand the information from depths of the universe by studying neutrinos,and trace the origin of the universe,in order to solve some core issues in the field of cosmology,such as positive and negative material asymmetry.The one of core issues in international neutrino research is the quality order of the neutrinos,which not only can help people to correctly understand the microscopic particle physics laws,but also has important influence on cosmology,astrophysics and geophysics research.The Jiangmen Underground Neutrino Observatory(JUNO)is located in Jinji town,Kaiping city,Jiangmen city,Guangdong province.It is designed to resolve the neutrino mass hierarchy using precision spectral measurements of reactor antineutrino oscillation.Detector Control System(DCS)is an important component of the JUNO,which is used to monitor the parameters affecting the performance of the detector for long-time running and control in order to achieve long-term stability of the detector performance.DCS is built in the pre-research phase of experiment.The design is the same as JUNO detector but differs in size.It is one-quarter of the JUNO detector.It established in Hall 4 at IHEP(Institute of High Energy Physics Chinese Academy of Sciences).In this thesis we mainly research and realize the data acquisition and storage DCS,in order to achieve web data for remote monitoring at the same time.Collecting and storing the data from all kinds of subsystems of the detector,such as high voltage,PTH(pressure temperature and humidity),electronics,VME crate etc.It provide references for the researchers to do the physical analysis.The thesis will focus on the development of data acquisition and storage software in Eclipse RCP based on Linux and the realization of the remote monitoring system through web server.The PyEpice function library is a bridge of Python language and EPICS Channel Access.It can collect and save data from EPICS IOC to data acquisition and storage software.JDBC is used for storage and collecting data to MySQL database.With the use of LAMP(Linux + Apace + PHP + MySQL)it people can build web server to display the data from MySQL database in web page.It is a good method of realization of the remote monitoring of the real-time operation information and historical operating status of each subsystem in experiment.This thesis begin with the data acquisition of JUNO detector prototype control system.And then is database development based on MySQL.Next is the web page monitoring system of JUNOMINDCS.In order to meet theJUNO detector control system need of collecting and storing big data in the future,the test for data acquisition and storage software and analysis of the results are performed by us.
