The scale and capacity of an accelerator depends upon such factors as the size of its storage rings, how much energy its continuously moving electrons hold, and the num er of beamlines it provides: Hence, this giant lamp with a circumference of 120 meters is the storage ring, and the beamlines emanating from it in every direction are like the light beams given off by a lamp.
加速器的規格或功能，就是以儲存環的圓周大小、維持運行的電子能量多寡，以及提供光束線的數目等來衡量。所以，這盞圓周長達一百二十公尺的巨燈就是儲存環，從它四周拉出來的光束線，就像從燈裡散射出來的光芒一樣，只是，所有的光源都被包裹在真空管道裡，肉眼不易看到。
