    ABOUT NEW MATHEMATICAL METHODS OF THE STRUCTURE ANALYSIS OF EUTECTOID COLONIES OF PEARLITIC STEELS

    No full text
    The algorithm for mathematical description of the pearlitic steels microstructures is offered. It is shown that the mathematical models of microstructures, constructed with use of frequency distributions of eutectoid colonies of pearlitic steels by inter-plate distances, enable to estimate the degree of microstructure heterogeneity

    POLAR-2 is a follow-up GRB mission of POLAR, which has observed low levels of polarization degree and a temporal evolution of the polarization angle, indicating that time resolved studies of γ\gamma photons polarization are required to constrain theoretical emission models of GRB’s. POLAR-2 detector aim to put in space a detector with one order of magnitude sensitivity improvement versus POLAR. POLAR-2 will be the most sensitive GRB detector covering half of the sky. The instrument, proposed by an international collaboration, was selected to be launched in 2024 to the China Space Station and operate for at least 2 years. POLAR-2 will use same plastic bar concept then POLAR but will be readout by SiPMT. The payload will also feature a spectrometer. The instrument is foreseen to perform detailed polarization measurements of at least 100 GRBs
