论文摘要
我们以数值分析超层析电子的辐射和通道特性，并通过在直型单晶钻石底物上生长的定期弯曲的钻石晶体传播。这样的系统可以称为杂晶，它们是实现晶体下降器的实验实现样品之一。我们指出，在这样的系统中，弹丸的通道和辐射特性对弹丸颗粒的能量以及梁传播方向敏感，即颗粒的光束是从底物的侧面还是从定期弯曲晶体的侧面进入晶体。做出的预测对于设计和实现新的晶体下输出剂的实现很重要。
We analyze numerically the radiation and channeling properties of ultrarelativistic electrons and positrons propagating through a periodically bent diamond crystal grown on a straight single-crystal diamond substrate. Such systems can be called hetero-crystals and they are one of the experimentally realized samples for the implementation of crystalline undulators. We state that in such systems the channeling and radiation properties of projectiles are sensitive to the projectile particles energy as well as on the beam propagation direction, i.e. on whether the beam of particles enters the crystal from the side of substrate or from the side of periodically bent crystal. The predictions made are important for design and practical realization of new crystalline undulators.
