我们设计了一块MediPix2单光子计数芯片与通用串行总线(USB)的接口板，USB是目前应用最广泛的PC接口。所有必要的探测器支持集成到一个紧凑的系统(80×50×20mm3)中，包括探测器偏置源(高达100V)。电源是从USB连接提供的电压内部获得的，因此不需要外部设备。该解决方案允许实现测量设置的最大便携性。最显著的优势之一是支持背面脉冲处理。电离粒子产生的电荷在偏置电路中测量，可用于光谱目的或用于触发。在目前的设计中，这种光谱的能量分辨率约为44keV。接口板的设计是为了与现有的带有一到四个MediPix2芯片的芯片板连接。
We have designed an interface board between the Medipix2 single photon counting chip and Universal Serial Bus (USB), which is presently the most widespread PC interface. All necessary detector support is integrated into one compact system (80×50×20mm3) including the detector bias source (up to 100V). Power supply is internally derived from the voltage provided by the USB connection, so no external device is required. This solution allows to achieve maximum portability of the measurement setup. One of the most significant advantages is the support of back-side pulse processing. The charge generated by an ionizing particle is measured in the bias circuit and can be used for spectroscopic purposes or for triggering. With the present design, the energy resolution of such spectrometry is about 44keV.The interface board has been designed for connection with present chip-boards carrying one or four Medipix2 chips.
