However, CCS technology is not without critics, who warn it might discourage efforts to cut CO2 emissions.

分析师观点出现分化。Evercore ISI 认为,IBM 早已向客户提供多种现代化路径,主机客户仍因可靠性、吞吐量、安全性等因素坚持使用该平台,并重申对 IBM 的「跑赢大盘」评级。

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?”)
