LCFI合作正在为国际直线对撞机（ILC）的顶点探测器（VXD）开发传感器，读出电子设备和机械支撑结构。需要高速读出以确保由于ILC处的对产生背景而导致的占用保持在1%水平以下。为了满足这一要求，人们开发了列并行CCD（CPCCD）和列并行读出芯片（CPR）。CPCCD必须在50 MHz的时钟频率下工作，由于传感器电容相对较大，这代表了一个困难的技术挑战。平面变压器，它可以用来提供所需的20 A的时钟电流的设计和性能进行了说明。(C)2009爱思唯尔有限公司版权所有。
The LCFI Collaboration is developing the sensors, readout electronics and mechanical support structures for the Vertex Detector (VXD) of the International Linear Collider (ILC). High-speed readout is needed to ensure that the occupancy due to the pair production background at the ILC is kept below 1% level. In order to satisfy this requirement, Column Parallel CCDs (CPCCDs) and Column Parallel Readout chips (CPRs) have been developed. The CPCCD has to operate at a clock frequency of 50 MHz, which represents a difficult technical challenge due to the relatively large sensor capacitance. The design and performance of planar transformers, which can be used to provide the required 20 A clock current, are described. (C) 2009 Elsevier B.V. All rights reserved.
