The flange design of the camera housing, including the Timepix hybrid pixel detector in the centre (Supplementary Fig. S1). The tiled detector assembly holds four Timepix quads (512 × 512 pixels each). The dark grey top layers pointed out by the arrows represent the sensitive silicon layers of a pair of Timepix quads and the light grey slabs below represent the chip board. The gaps between the chips are necessary to accommodate the wire bonds to the readout boards.
