14 SphinX calibration BESSY synchrotron RAS Meeting 9 May 2008 Janusz Sylwester, Poland: Ongoing and future solar X-ray experimenting March 2nd 2008 D3 Berlin February 26th 2008

15 How it looks from the tests BESSY Berlin Synchrotron: - All detector linearity: perfect (0.1% ) over 0.8-14.5 keV; dynamic range 10 4. - absolute response known to better than 5% against reference synchrotron source. - pile-up matrices known as measured from X-ray 4 crystal monochromator spectra obtained at 8 energies between 1.5 and 8 keV 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.

16 The measurement environment, bcgd: ~few cts/s up to 10 3 cts/s (SAA) SAA Night RB RB Night Flare CORONAS-F Previous CORONAS-F orbit Important pahases S/C X-ray day S/C optical day S/C optical night S/C X-ray night  Terminator crossing

17 Time stamping mode D1, D2 or D3 rates < 10 3 /s Time stamping mode from: D1, D2, D3, D4 –2 Bytes for processor time of the detector event start –1 byte for the amplitude –Allows to determine the difference between events to within 2 μ s ~2/1000 accuracy –Absolute timing to within 0.001s against UT Expected rates D1= 10 3 events/s (event: Amplitude 1byte, time 2 bytes)-3 KB/s D2= 10 events/s, D3= 10 events/s, D4= 10 events/s Total: 3Kbytes/s – can last for ~10000s (3 h) each dump – may cover 100% cycle with compression

18 Waiting time analysis – is the process at low count rate Poissonian? Wheatland, The Astrophysical Journal, Volume 679, Issue 2, pp. 1621-1628, 2008 Radioactive sources give an ideal example of the statistics To what degree the arrival times of photons from the „quiet” corona have „no memory” i.e they have the exponential waiting time distribution? (Models for flare statistics assume or predict that flares are independent events- however this is under question) The primary task for the initial part of the mission where the activity is expected to be low.

21 Recent GOES & RHESSI

22 Energy Calibration 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

23 Terminator transit: Profile of Earth atmospecric absorption 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

24 SphinX firsts http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/The_Sp hinX_Instrument_on_CORONAS-PHOTON http://sprg.ssl.berkeley.edu/~tohban/wiki/index.php/The_Sp hinX_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.

25 Instrument satus 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

26 The FFU unit (filter-fluorescence unit) Filter-Fluorescence Unit (FFU) layout This unit will be active all the time: time stamping < 1000 cts/s or spectra (256 bins)
