论文摘要
在[1]中，针对高强度的非相关质子束在[1]中介绍了径向耦合的同轴快速杯设计。在这项工作中，我们讨论了在相对较低的强度离子光束的背景下进行纵向电荷剖面测量值的修改。讨论了新设计的粒子和时域电磁模拟，重点是避免场稀释，同时讨论了新德里IUAC即将到来的高电流喷射器程序的相对较低的强度离子束[2,3]。估计了二级电子发射的轮廓畸变，并讨论了抑制它们的策略。
A radially-coupled coaxial fast Faraday cup design was presented in [1] for high-intensity non-relativistic proton beams. In this work, we discuss a modification of that design in the context of a relatively lower intensity ion beam for longitudinal charge profile measurements. Particle-in-cell and time domain electromagnetic simulations of the new design with a focus on avoiding field dilution while generating enough signal for relatively lower intensity ion beams at the upcoming High Current Injector Programme at IUAC, New Delhi [2,3] is discussed. Profile distortions from secondary electron emission are estimated and strategies to suppress them are discussed.
