Pi explains that getting electrons to approach the speed of light, and then storing them in stable conditions in a channel five micrometers wide (that's one-fifth the diameter of a strand of hair) is a daunting task. The stability of the vacuum, the temperature and electricity can all influence the results.
皮敦文解釋，一團電子要以接近光速的速度，在儲存環寬僅五微米（相當一根頭髮的五分之一）的軌道內穩定運行，真空狀況、溫度、電源供應的穩定與否… …，都會影響到成果。
