原位存储图像传感器 (ISIS) 是一种单片有源像素传感器，每个像素中都带有存储单元。存储单元被实现为 CCD 寄存器。该传感器的这一特性和其他特性使 ISIS 成为一款优秀的探测器设备，将用于国际线性对撞机 (ILC)，这是一种电子-正电子加速器，建议质心能量约为 500GeV。该传感器可以做得非常薄，同时保持高信噪比。可以以相对较低的时钟速度在串串之间读取存储单元，从而限制功耗。实际信号电荷存储在势阱中而不是电容器上，从而最大限度地降低了对电磁干扰的敏感性。本文介绍了第一个 ISIS 原型机的第一次光束测试的结果。所做的测量包括信噪比、位置分辨率和效率。
The in situ storage image sensor (ISIS) is a monolithic active pixel sensor with memory cells in each pixel. The memory cells are implemented as a CCD register. This and other features of the sensor make the ISIS an excellent device for detectors that will be used at the International linear collider (ILC), an electron-positron accelerator with a proposed centre-of-mass energy of around 500GeV. The sensor can be made very thin while retaining a high signal-to-noise ratio. The memory cells can be read out between bunch trains at a relatively low clock speed, hence limiting power consumption. The actual signal charge is stored in potential wells and not on capacitors, minimizing the sensitivity to electromagnetic interference. This paper presents the results of the first beam test of the first ISIS prototype. The measurements made include the signal-to-noise ratio, position resolution and efficiency.
