Hamamatsu Photonics(C7942)的CMOS型平板成像器已经在各种同步辐射实验中进行了性能测试。该探测器的探测面积约为120 mm×120 mm，像素为0.05 mm，帧速率为2 S(-1)。商用的产品对能量低于15keV的X射线不敏感，但稍作修改就解决了这个问题。在小角散射、蛋白质结晶学和医学成像实验中获得的图像都是高质量的。读出速度快，面积大，有利于实时成像。尽管它的噪声水平高于目前同步辐射实验中使用的面探测器，但在无法使用其他大型探测器的实验中，它尤其有用。其相对较低的价格(约3万美元)使其成为探测器选择中的独特选择。
The performance of a CMOS flatpanel imager from Hamamatsu Photonics (C7942) has been tested in various synchrotron radiation experiments. This detector has a detection area of about 120 mm x 120 mm with 0.05 mm pixels, and a frame rate of 2 s(-1). The commercially available product was insensitive to X-rays with an energy lower than 15 keV, but slight modifications solved this problem. Images obtained in small-angle scattering, protein crystallography and medical imaging experiments were all of high quality. The fast readout and the large area are advantageous in real-time imaging. Although its noise level is higher than the area detectors that are currently used in synchrotron radiation experiments, it is particularly useful in experiments where other bulky detectors cannot be used. Its relatively low price (about 30,000 US dollars) makes it a unique option in the choice of detectors.
