Abstract
The physical boundaries of a fully-depleted CCD can lead to distorted field lines and non-uniform response. We study this response with a beam of X-rays constrained to a width of less than one pixel (15 \(\upmu\)m), and a system to map the CCD response as a function of transverse position.
