1. Example data of SDCCD @sor
Visible lights from scintillator form a relatively small symmetric islands.
20 keV
70 keV
500 μm
500 μm

2. Position resolution of the SDCCD
We can determine the point of interaction of X-ray photons within a pixel.
Integration mode
Event pixel
Sub-pixel resolution

3. Cross section of the shadow
Integration mode Center of gravity Subpixel resolution

4. E-PHA relation

7. We are now developing a large format CCD for Sumit SDCCD.
Pixel size is 15 mm square.
Format is 2k x 4k (either full frame mode or frame transfer mode)
The effective area will be 3cmx6cm.
Pch type CCD with a depletion layer thicker than 200mm.
Buttable type CCD.
Performance of the test device is good enough to cover the energy range above 0.3 keV.
