CCD sensor for low-level X-ray detection

Paul Boughton
Hamamatsu Photonics is introducing the C10650 X-ray TDI CCD sensor for low-level X-ray detection. Compared to conventional line sensors, such as the Hamamatsu C9750 series, which are based on CMOS technology, the TDI CCD provides high sensitivity, high resolution (sub 50micron pixel size) and high dynamic range. The TDI-CCD allows for faster imaging compared to conventional X-ray CCD cameras - up to 2280 lines can be read per second. This allows the C10650 to be used in industrial applications requiring higher speed and/or image quality.
The C10650 incorporates a fibre-optic to shield the CCD from incident X-rays and the CsI scintillator is optimised for 20-80kVp operation. The X-ray camera module provides a 12bit digital output via a camera link interface and operates from a 15V power supply. The C10650 is available in two formats, 3072 x 128 pixels and 4608 x 128 pixels. With a large CCD pixel size of 48micron in each case, this gives a total imaging area of up to 220mm x 6mm.
The C10650 can be adopted in a wide variety of NDT inspection applications, including mining, packaging, pharmaceuticals, pipelines, moulded metallic components, tyres, turbines, building materials, bone and glass in food stuffs, bottles, tin cans and many more.
