Remote-controlled Synchronous System For The ICF High-speed Physical-diagnosis Experiment

A powerful concentrative control system for data acquisition and management is necessary in Inertial Confined Fusion (ICF) experiments. In the ICF high-speed physical-diagnosis experiment, the joint debugging experiments can be triggered synchronously by the synchronous system, and the entire physical diagnosis system can be high-efficiency and proper. The time delay and time resolution of the trigger signals for each detectors or data processing subsystem are different. High-precision remote-controlled synchronous system is one of the significant subsystem in high-speed ICF physical-diagnosis system.In order that the framework could satisfy the increasing requirement of ICF rasearch and be used widely in other fields, synchronous system based on network-distributed mode was designed. This thesis described the research and design of the high-precision remote-controlled synchronous system for high-speed physical diagnosis in large ICF experiments.In the thesis, the significance and the characteristic of the synchronous subsystem were introduced first. Then the scheme and the main technique for the synchronous system were described in detail. Adopting the fast instantaneous electronics, the high-precision remote-controlled synchronous system based on FPGA was designed. Using the FPGA as the intelligent control chip,16-channels signal pulses with the high precision and good stability were achieved. The16-channels signal pulses can be regulated independently and maintained the precision of5ns and the pulse width from0to20s. With the development of the network, we bringed forward a holistic scheme for the synchronous system, in which every data acquisition equipment are triggered by the system through network communication. A dynamic Web program and a Server application were designed under the Delphi7, through which the concentrative management of the diagnostic equipments was realized. The research in high-precision remote-controlled synchronous system has great significance in enhancing the dependability when we research the phenomenon of ICF.The significance and innovations of this thesis are as follows:1) Regarding the dependability as the precondition, the16-channels signal pulses can be regulated independently and maintain the precision of5ns and the pulse width from0to20s.2) The remote-controlled mode based on distributed network was realized by the dynamic Web program.3) For the widely use in other applications, an optical, an electrical burst mode circuitry and a manual mode circuitry was designed in this system.
