直线对撞机气味识别(LCFI)合作已经成功开发出第一个新型颗粒探测器的原型--原位存储图像传感器(ISIS)。该器件非常适合未来的国际直线对撞机(ILC)对顶点探测器的苛刻要求，将电荷耦合器件(CCD)的电荷存储能力与在CMOS成像器中常用的读出功能结合在一起。与典型的CCDS相比，ISIS避免了高速读出的需要，并提供了低功耗操作、低噪声、高抗电磁干扰和更高的辐射硬度。ISIS是ILC最有前途的顶点探测技术之一。在本文中，我们描述了p井的电荷屏蔽性能的测量，p井用于保护存储寄存器免受寄存器寄存器的寄生电荷收集的影响，它是器件工作的核心。结果表明，p势垒可以抑制寄生电荷收集近两个数量级，满足实际应用的要求。
The Linear Collider Flavour Identification (LCFI) collaboration has successfully developed the first prototype of a novel particle detector, the In-situ Storage Image Sensor (ISIS). This device ideally suits the challenging requirements for the vertex detector at the future International Linear Collider (ILC), combining the charge storing capabilities of the Charge-Coupled Devices (CCD) with readout commonly used in CMOS imagers. The ISIS avoids the need for high-speed readout and offers low power operation combined with low noise, high immunity to electromagnetic interference and increased radiation hardness compared to typical CCDs. The ISIS is one of the most promising detector technologies for vertexing at the ILC. In this paper we describe the measurements on the charge-shielding properties of the p-well, which is used to protect the storage register from parasitic charge collection and is at the core of device's operation. We show that the p-well can suppress the parasitic charge collection by almost two orders of magnitude, satisfying the requirements for the application.
