The Design of a Plastic Scintillating Fiber-Based Array for Online Tritium Monitoring in Water

The values of 1, 2, and 3 in the result *. txt file represent the diameter of the cladding free scintillation fiber as 1, 2, and 3 mm. The first column of the file shows the number of fibers, the second and third columns show the detection efficiency and error (based on Gaussian distribution), the fourth and fifth columns show the error of MDAC and MDAC (according to the error propagation formula), and the remaining columns are discarded data. The cfc and sic=*. txt files represent the data of PTFE and silicone coatings on a 1mm diameter uncoated scintillation fiber, respectively. Among them, 0.001.01, 0.1,1 represent the coating thickness (mm), and the data meaning is basically the same as the result *. txt file. Only the first 5 columns of data need to be analyzed. Note that c=0 represents the data of a 1mm diameter uncoated scintillation fiber. The result_curve.txt file represents the relationship between the detection efficiency and the number of MDAC and fibers for a cladding free scintillation fiber with a diameter of 1 mm under different curvatures. The first column is the number of fibers, the second column is the curvature (mm-1), the third and fourth columns are the detection efficiency and error, and the fifth and sixth columns are the errors of MDAC and MDAC, respectively. The meaning of 'result_curve.txt' represents the relationship between ANN, detection efficiency, and MDAC of a cladding free scintillation fiber with a diameter of 1 mm under low fiber filling density conditions, similar to 'result_curve.txt', except that the second column represents the dimensionless value ANN. The meaning of result_C is the relationship between δ E/E and MDAC for a 1mm diameter uncoated scintillation fiber with high fiber filling density, omitting the detection efficiency. The first column represents the number of fibers, the second column represents δ E/E, and the third and fourth columns represent the errors of MDAC and MDAC, respectively. The meaning of longth.txt is the detection efficiency of cladding free scintillation fibers with a diameter of 1 mm of different lengths, where the first column is the length (mm) and the second column is the detection efficiency (%).
