They also needed an alternative to conventional X-rays. In a clinical linac, X-ray photons are produced by dumping high-energy electrons into a bremsstrahlung target, which is made of a material with a high atomic number, like tungsten or copper. The target slows the electrons, converting their kinetic energy into X-ray photons. It’s an inherently inefficient process that wastes most of the beam power as heat and makes it extremely difficult to reach the ultrahigh dose rates required for FLASH. High-energy electrons, by contrast, can be switched on and off within milliseconds. And because they have a charge and can be steered by magnets, electrons can be precisely guided to reach tumors deep within the body. (Researchers are also investigating protons and carbon ions; see the sidebar, “What’s the Best Particle for FLASH Therapy?”)。关于这个话题，新收录的资料提供了深入分析
3月8日消息，十四届全国人大四次会议今天举行外交主题记者会。外交部长王毅在会上介绍，我国已对50个国家实施了单方面免签，同29个国家全面互免签证，去年免签入境的外籍人士比例高达73%。下一步将继续优化人员往来政策，进一步释放免签红利，完善各项配套服务，让外国朋友来华旅游生活更加便捷舒适，让中国公民“走出去”也更加顺畅安全。，推荐阅读新收录的资料获取更多信息
