Abstract

The study is devoted to the development of a data collection module of the electromagnetic calorimeter of the Super c-τ factory collider. The data collection module is one of the main parts of the data acquisition system of the electromagnetic calorimeter. It is designed for analog and digital signal processing of scintillation counters, calculating its main characteristics (amplitude, time of occurrence and quality of fitting), and participates in the launch of the detector data acquisition system. A prototype of the module on which the module will be debugged and the algorithm of the device will be checked is being developed. The algorithm of the module includes the calculation of signal characteristics and the formation of packets for data transmission. Signal characteristics are calculated by approximating a function defined either by the least squares method or by the method of χ2 function minimization. In the course of a mathematical experiment, it was found that the method of χ2 function minimization gave more accurate calculation values than the least squares method. However, it requires an experiment with scintillation counters to determine the necessary coefficients. Therefore, the coefficients of the approximating curve are determined by the least squares method in the prototype and the method of χ2 function minimization is used in the module. Based on the results obtained, an algorithm of the module operation was compiled, which was then implemented in the field-programmable gate array Altera Cyclone 10GX.


Keywords: electromagnetic calorimeter, data acquisition system, scintillation counters, least squares method, method of ?2 function minimization
