The BESSY synchrotron input spectrum (red) with overplotted response of SphinX D2 detector (black). Nominal effective areas have been used. The agreement is better than 5% in the energy band where SphinX detectors

are the most sensitive.

Synchrotron:

- All detector linearity: perfect (0.1% ) over 0.8-14.5 keV; dynamic range 104.

- absolute response known to better than 5% against reference synchrotron source.

- pile-up matrices known as measured fromX-ray 4 crystal monochromator spectra

obtained at 8 energies between 1.5 and 8 keV

  • D1,D2,D3 solar induced fluorescence spectra of pure elements
    • During flares ~> M1
    • Until 10^6 cts collected for each detector
    • Approximately each month
    • If v. quiet condition then on the command from the ground for 10 min

  • X-ray terminator crossing algorithm operational on board
    • Predict the entry/exit to within few seconds
    • Spectra 256 energy bins each 0.1 sec give at least 1 km resolution in the vertical Earth absorption profile
    • Time stamping or spectral mode depending on the flare flag

SphinX firstshttp://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/The_SphinX_Instrument_on_CORONAS-PHOTON
  • SphinX will measure absolute element abundances using line features due to neon, magnesium, silicon, sulphur, argon, calcium, iron and nickel in various levels of solar activity (quiet Sun, active regions and flares). It should therefore be in a strong position to give a definitive answer to the continuing debate about the dependence of coronal abundances of elements on their first ionization potential, the so-called FIP effect.
  • SphinX will obtain the first absolutely calibrated solar X-ray spectra in the 0.8--15 keV range. In particular this will help us to understand the RHESSI continuum observations in this difficult range.
  • SphinX will also study quiet coronal heating processes via photon arrival time--distance analysis (the arrival time of an X-ray photon will be measured to a couple of microseconds); X-ray oscillations in the <1 to 500 s period range; and transient ionization in flares.

  • Flight model at the Moscow „factory” undergoing final electro-magnetic & teelmetry compatibility tests
  • On November 30, TESIS ( a mother instrument for SphinX) is coming for a final maintenance tests to FIAN (MK+WT) will reload the flight programme
  • The Coronas-Photon launch is expected before the end of 2008 a X-mas present?
  • Ground sector of software v1 ready (Czech contribution under guidance od Szymon)
    • 2 mirror servers (Wrocław, Ondrejov)
    • Automatic data access to FIAN SphinX data stream (~12 hours maximum delay if 2 dumps/24h)
    • Automatic reduction to Level2
    • Data publishing to the public access area (90% data will go there decision taken by the duty scientist)
    • Automatic flare event catalogue creation start,max, end, class, Tmax, Emmax, rise phase dur L, H, EMmax-Tmax delay
    • Auxiliary data available: GOES, RHESSI, SOXS
