But there’s also that annoying, gnawing truth: You don’t know what you don’t know. This has, for decades, been an apt adage for describing life in this experimental orbital colony. Eventually, though, different aphorisms will come into play. Yes, it’s true: You don’t know what you don’t know. But we do know that all good things come to an end. And that what goes up must come down.
Instead of a continuous stream, the electron beam is divided into nanosecond-long bunches—billions of electrons riding the radio-frequency field like surfers. Inside the accelerator’s cavities, the field flips polarity 12 billion times per second, so timing is everything: Only electrons that arrive perfectly in phase with the accelerating wave will gain energy. That process repeats through a chain of cavities, each giving the bunches another push, until the beam reaches its final energy of 200 MeV.。新收录的资料对此有专业解读
