WidePIX 5×5 Curved

WidePIX 5X5 Curved is a large area imaging camera with a curved continuously sensitive surface. The curvature of the camera of 15 cm has been optimised for the small animal imaging applications.

Description

Each Timepix tile consists of an edgeless silicon sensor. The edgeless sensor technology allows all of the tiles to be tightly packed together from all sides. Thus the whole imaging area of the camera is fully sensitive to the radiation – there are no gaps between the tiles in the image.

The minimum detectable energy is typically 5 keV in the case of X-ray photons. The intrinsic spatial resolution of the camera is defined by pixel size, which is 55 µm. The pixels situated on the borders of the tiles are 2.5 times larger in one direction. The corner pixels of tiles are 2.5 times larger in both directions.

The camera is connected to the controlling computer via a USB 2.0 cable with a readout time of 0.65 seconds per frame. The thermal stabilisation of the camera is provided by an active water cooling system with chiller. The power consumption is 25 W.
