ABSTRACTAt INFN-LNS we have developed a new kind of gamma mini-sensor, which allowed to implement a prototype array of modular sensors for online monitoring of radioactive waste. The sensors are based on Silicon PhotoMultipliers and scintillating fibers sensitive to gamma radiation, that have to be placed in a repository in shape of a fine grid, around each single waste drum. We simulated the counting response of thin scintillating fibers and verified the results with measurements using radioactive sources. Front-end electronics and an FPGA-based counting system were developed to handle the field data, also implementing data transmission, a graphical user interface and a data storage system. Moreover a test of four sensors in a real radwaste storage site was performed with promising results.

According to the trend of the development of the computer system bus more, designs the general high-speed data storage system based on computer platform structure.Put forward the "one-way chain" cache structure, to avoid the computer operating system of real-time data transmission, the influence of the multithreaded mode data transmission and storage of parallel processing.According to the basic principle of data storage in a computer system, put forward the standard file operations function replace special instruction set, the method of implementing the SCSI disk array storage at a high speed.Test results show that the data storage system based on computer platform with more generalization method to achieve the high speed of data storage.
