抽象。目前对电荷耦合器件（CCD）中电荷转移动力学的理解是，电荷在时钟序列中从一个相位快速移动到下一个相位，并且密度非常低，以至于相间区域中的电荷捕获可以忽略不计。然而，电子成像中心开发的模拟能力，包括电子密度模拟的直接输入，使人们有可能进一步调查这一假设。作为欧几里得CCD 273器件辐射测试活动的一部分，使用阱泵浦方法获得了数据，该方法可用于识别和表征CCD内的单个缺陷。结合这些数据与模拟，我们发现，捕获过程中的相位之间的电荷转移确实是必要的，以解释数据分析的结果。这一结果不仅会影响陷阱泵浦理论和如何进行陷阱泵浦，而且会影响如何以最佳方式读出辐射损伤的CCD。
Abstract. The current understanding of charge transfer dynamics in charge-coupled devices (CCDs) is that charge is moved so quickly from one phase to the next in a clocking sequence and with a density so low that trapping of charge in the interphase regions is negligible. However, simulation capabilities developed at the Centre for Electronic Imaging, which includes direct input of electron density simulations, have made it possible to investigate this assumption further. As part of the radiation testing campaign of the Euclid CCD273 devices, data have been obtained using the trap pumping method, a method that can be used to identify and characterize single defects within CCDs. Combining these data with simulations, we find that trapping during the transfer of charge among phases is indeed necessary to explain the results of the data analysis. This result could influence not only trap pumping theory and how trap pumping should be performed but also how a radiation-damaged CCD is readout in the most optimal way.
