Nominal effective areas have been used. The agreement is better than 5% in the energy band where SphinX detectors are the most sensitive. BESSY Berlin 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 from X-ray 4 crystal monochromator spectra obtained at 8 energies between 1.5 and 8 keV The measurement environment, bcgd: ~few cts/s up to 103 cts/s (SAA) SAA Night Previous CORONAS-F orbit CORONAS-F RB RB Night Flare Important pahases • S/C X-ray day • S/C optical day • S/C optical night • S/C X-ray night Terminator crossing Time stamping mode D1, D2 or D3 rates < 103/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 μs ~2/1000 accuracy – Absolute timing to within 0.001s against UT Expected rates D1= 103 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 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.

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 Xray photon will be measured to a couple of microseconds); Xray oscillations in the <1 to 500 s period range; and transient ionization in flares.
