Abstract
We report here the results of polarized X-ray detection with a charge-coupled device (CCD). The photoelectron produced in the CCD is mainly ejected along the electric vector of the incident X-ray. This means that the primary charge cloud mainly remains in the depletion layer if the photo absorption occurs in it. Therefore, a primary charge cloud is elongated towards the X-ray polarization vector. The range of the electron in the silicon is roughly expressed (E/10 keV)1.75 micrometers where E is the electron energy in KeV. Therefore, the range of the photoelectron in this energy region is at most two-pixel length. We investigated the relation between the direction of the linear polarization of X-rays and the statistics of the charge cloud shape.
