Skipper电荷耦合器件（Skipper-CCD）的发展是用于感测非常弱的电离粒子的重大技术突破。该传感器允许通过明确确定由每个单元或像素收集的电荷信号来达到硅材料作为电荷信号传感器的最终灵敏度，即使对于单个电子-空穴对电离也是如此。该技术的广泛使用受到限制，因为缺乏特定设备来操作传感器的最终性能。在这项工作中，一个简单的，单板跳跃CCD控制器，目的是在高灵敏度的科学应用中的探测器的操作。本文介绍了低阈值采集（LTA）的主要组成部分和功能，以及连接到Skipper-CCD传感器时的实验结果。测量结果表明，前所未有的深亚电子噪声为0.039 e$^-_{rms}$/pix的5000像素的测量。
The development of the Skipper Charge Coupled Devices (Skipper-CCDs) has been a major technological breakthrough for sensing very weak ionizing particles. The sensor allows to reach the ultimate sensitivity of silicon material as a charge signal sensor by unambiguous determination of the charge signal collected by each cell or pixel, even for single electron-hole pair ionization. Extensive use of the technology was limited by the lack of specific equipment to operate the sensor at the ultimate performance. In this work a simple, single-board Skipper-CCD controller is presented, aimed for the operation of the detector in high sensitivity scientific applications. The article describes the main components and functionality of the Low Threshold Acquisition (LTA) together with experimental results when connected to a Skipper-CCD sensor. Measurements show unprecedented deep sub-electron noise of 0.039 e$^-_{rms}$/pix for 5000 pixel measurements.
