System for γγ coincidence spectrum processing with preliminary data compression

The system of the γγ coincidence spectrum processing with the preliminary data compression is described. For compressing the two-dimensional spectrum the decomposition of matrix-spectrum on singular values (SVD-transformation) is suggested to use. This allows one to save the magnetic tape needed for data storing and to avoid data sorting during their handling. The numerical realization of the SVD-transformation is described for the measurement with the data compression. It is shown that parts of spectrum reconstructed after compressing differ from the original ones only in smaller level of statistical fluctuations. The results of comparison of the data processing for compressed and uncompressed spectra are shown
