Abstract:
The results of calibration of new semiconductor detectors for monitoring the solar ultraviolet radiation flux in the Lyman-alpha line (Lα, 121.6 nm) onboard the geostationary spacecraft "Electro" of the Russian Hydro-meteorological service are presented. Calibration was carried out due to the source of synchrotron radiation of relativistic electrons on the channel of the electron storage ring VEPP4. A radiation beam in individual narrow parts of the spectrum was formed by using the “Cosmos“ metrological complex at the Siberian International Center for Synchrotron Radiation. of relativistic electrons of the Institute of Nuclear Physics SB RAS .. The analysis of spectral sensitivity curves showed that the sensitivity of the detectors can vary greatly (by ~30%). Using the model spectra of the ultraviolet radiation of the Sun, the contribution of P to the detector signal from the Lα line and from the spectral region above ~ 122 nm was calculated. As a result of the analysis of model calculations for various levels of activity, it was shown that the value of P can be very different for different sensors: P is 30% –60% at a low level of solar activity and 50% –70% at high level. This result indicates the need to calibrate all the channels of each flight instrument and take into account, when monitoring space weather, the dependence of the contribution P to the VUSS-E signal from the Lα line on the solar activity level.
