TEST RESULTS WITH 2KX2K MCT ARRAYS Finger, G, Dorn, R.J., Mehrgan, H., Meyer, M., Moorwood A.F.M. and Stegmeier, J. European Southern Observatory Abstract: The performance of both an LPE 2Kx2K engineering grade and a science grade array have been evaluated. Both arrays have a cut-off wavelength of c=2.6 µm. At an operating temperature of 60 K, the dark current of the science grade array is 0.004 e/s. The peak quantum efficiency of the science grade array is 84.4%. ...

The observation of active regions with RATAN-600 and the Beijing Astronomical Observatory spectrograph in the decimeter wave band shows an existence of a long-term non-thermal emission of active regions in continual (a halo) and flaring (flares and micro flares) components. The observation-compatible models have been devised specifying the nature of continuum as a radiation originating in the non-linear interaction of plasma waves at the upper-hybrid frequency. ...
