(a) Three stages of charge collection in a pnCCD. (1) Generation of charges inside the depleted bulk by irradiation. (2) Separation of charges by electric field. (3) Collection of charges in potential minima near the front contact and later on transfer to readout nodes. (b) Schematic view inside the fully depleted volume of the pnCCD. (c) and (d) pnCCD system of a 256 × 256 frame-store pnCCD, comprising a ceramic board with filter units and temperature control. The larger lower part of the pnCCD is the image area (75 µm × 75 µm pixels), the upper smaller part is the frame store area (51 µm × 75 µm pixels). The two CAMEX chips are wire bonded to the on-chip JFET of the pnCCD.
