High temporal resolution multimode panoramic photospectropolarimeter (MPPP)

Russian version

    The modernization of the instruments and software complex of the MANIA experiment for searching for and studying the variability of astrophysical objects with a temporal resolution of 10-6s has been completed. The designed observation complex, having no analogues in the world, provides the possibility of registering photon fluxes from optical sources with a microsecond temporal resolution and determining their energy and polarization characteristics. As radiation receivers, two position-sensitive detectors are used with sensitivity maxima in the long- and short-wave regions of the spectrum (V. Debur et al., NIM in Physics Research, 2003, A 513, 127., V.L. Plokhotnichenko et al., AB SAO, 2020, 75. 1. pp.65-75) with the determination of the registration moments of quanta by the chronometric "Quantochron 4-48" instruments (V.L. Plokhotnichenko et al., AB SAO. 2009, 64, 2, pp.204-210) and the EMCCD camera. The operating modes provided by the complex with the measurement of 3 Stokes parameters are: 1 - the broadband mode, 2 - the high-sensitivity mode with an EMCCD camera, 3 - the UBVR photometric mode, 4 - the spectral mode with an Abbe prism, 5 - the spectral mode with a diffraction grating, see the figure. They are changed remotely in 1-5 minutes, and the registration, storage, and reduction of data are provided by an information cluster consisting of 7 computers, which makes it possible to continuously register photon fluxes and their coordinates measured on detectors throughout the night with an accuracy of reference to UT of 0.1 ms. The results obtained from observations of X ray sources, flare stars, and optical pulsars demonstrate the effectiveness of using the designed complex in high-resolution astronomy and relativistic astrophysics.
