  flat panel sensor c9728dk-10 for diffraction, cassette type with usb 2.0 interface photodiode area: 52.8 52.8 mm www.hamamatsu.com 1 the c9728dk-10 is a high detection capability digital x-ray image sensor newly developed as a key device for x-ray diffracto- meters less than 18 kev. the device shape is thin cassette which incorporates on-chip high-resolution scintillator and a contro l board. an on-board usb 2.0 interface can realize fast data transfer with the c9728dk-10. structure the c9728dk-10 is comprised of a sensor board and a control board. mounted on the sensor board is a cmos image sensor chip made up of a two-dimensional active pixel amplifier array, row-scanning vertical shift register, and 8 shift register blocks. csi scintillator is directly deposited on the two-dimensional photodiode array. x-rays incident on the scintillator are convert ed to fluorescence, which then enters the two-dimensional photodiode array where electric charge is accumulated in each pixel according to the light inte nsity. each pixel has a low noise active pixel amplifier. the analog video signal from each pixel is held by the 1056 ch sample-and-hold circuit with a cds (correlated double sampling) circuit added, and is then output from each amplifier array by scanning the horizontal shift register. the control board converts the analog signal into a 14-bit digital signal, which is then output to a pc through the usb 2.0 int erface. horizontal shift register no. 1 horizontal shift register no. 8 pixel number active pixel amplifier array with directly deposited csi scintillator 12 1115136 1057 1056 1055 2112 1115135 2111 kaccc0617e timing pulse generator oscillator trgout a/d external power supply a.vdd, d.vdd (not attached) buffer amp buffer amp processing amp processing amp bias generator usb ic trgin fifo a/d fifo video data flat panel control (usb 2.0 interface) sensor board control board note: signals are read out in order of pixel number. vertical shift register kaccc0617ea active pixels readout * 1 low noise: 80 electrons 1032 1032 pixels (50 m pitch) 14-bit digital output (usb 2.0 interface) compatible with hamamatsu api (dcam-api) high-speed imaging: 3 frames/s high resolution features diffraction radiography * 1: the amplifier integrated in each pixel converts charge to voltage. since the amplifier input capacitance is small compared to the passive pixel type, imaging can be made with low noise and high sensitivity. applications
