Paper Abstract

A mesh experiment for the x-ray CCD enables us to specify the interaction position of the x-ray photon with subpixel resolution. There are two types of experiments: a single- pitch mesh experiment and a multi-pitch mesh experiment. Using the multipitch mesh experiment, we have established the method to measure the charge cloud shape inside the CCD produced by an x-ray photon. We can measure signal outputs from the pixel according to the interaction position of x- rays. Finally, we obtain, in detail, the charge cloud shape which can be well represented by an asymmetric Gaussian function. The symmetry of the charge cloud shape is probably due to the asymmetry of the electric field inside the CCD.
