X-Ray Detector Boards

Hangzhou Shalom EO offers a series of custom-tailored Detector Boards for X-Ray Imaging Systems. The products are line-scan x-ray Si photodiode detectors based on scintillators, integrated on data acquisition boards. These modules feature high responsivity and short integration time, moderate NEP (noise equivalent power), etc. combined with robust architecture of high radiation durability to ensure a long lifetime under x-ray flux and strengthened interfaces. The detector boards are apposite for applications in various fields associated with x-ray imaging and inspection, including baggage inspection, security screening, food testing, the mineral industry, etc. No matter where your interest lies Shalom EO could tailor the detector for incorporation into your systems to help you produce complete X-ray imaging solutions.

Each detector board produces End-Of-Scan pulses, which accommodate the aligning of individual boards into a continuous row of detector boards.

Compared to direct X-ray detection means such as CCDs, the detector modules using scintillators have the advantages of a wider detectable energy range and the ability to scan objects in large areas.

One layer or two layers of linearly pixelated crystalline/amorphous silicon photodiodes are coupled with scintillators on top of them. The double-layer versions allow Dual-energy Inspection, where the low-energy X-ray and high-energy X-ray are separated by the copper filter between two layers, with the pixel amount of unhindered access from 1x8 to 1x128 （1x8, 1x16, 1x32, 1x64, 1x128）, and customized pixel dimension/pitch, all the elements are integrated simultaneously. One could also select the scintillator materials for the X-ray detectors according to specific applications. In this case, Shalom EO recommends CsI(Tl), GOS ceramic, or CdWO4, since their spectrum of high light output matches well with the sensitive spectrum of the PDs.

Referring to the data acquisition boards, Shalom EO can provide our clients with different kinds of electronic readout circuits that are optional according to your specific application, including CMOS signal processing, ASIC, etc.
