16. Line profile (low energy tail) Oxygen-K (0.525 keV), H.V. = 1 and 5kV The effect of applied high voltage (5 kV) is almost negligible. Tail component is significantly smaller than that for XIS 1. 1 kV 5 kV Pulse Height Counts XIS1 (H.Katayama master thesis) XIS2-S2

17. Summary Cal. Data were obtained with Fe55 and spectrometer (~0.2-3 keV). E-PH, E-Resolution relations are as expected. Low energy tail component is smaller than that for XIS1 sensors. We find that X-ray flux from the generator is variable on long timescale. This has to be taken into account before calculating QE. BPSG layer thickness does not seem to be significantly thinner for FM sensors than for EU (preliminary).
