After collision, the energy condenses to create new particles that can be measured and tracked inside the complex particle detectors around the accelerator ring.

对撞之后，这些能量会生成一些新的粒子，它们可以在围绕着加速环的复杂粒子探测器里被测量并跟踪。

Meanwhile, the cooling system that circulates superfluid helium around the LHC's accelerator ring keeps the machine at minus 271.3 degrees Celsius (minus 456.34 degrees Fahrenheit).

与此同时，冷却系统使环超流氦沿对撞机的加速环循环，使其温度保持在零下271.3摄氏度(零下456.34华氏度)。

At full power, trillions of protons will race around the LHC accelerator ring 11, 245 times a second, travelling at 99.99 percent the speed of light.

全功率运行时，数兆的质子在大型强子对撞机的加速环中加速，一秒钟可绕行11245圈，速度达到光速的99.99%。

But the shut-down schedule also includes upgrades to all four of the LHC's detectors, the shielding of electronics, and even an overhaul of the ventilation system of the tunnel that houses the main accelerator ring.

The crucial point, and the reason for the excitement, is that both ATLAS and CMS (which are located in different parts of the ring-shaped accelerator tunnel of the LHC) have come up with the same results.

By 1968 he had concluded that they could be kept in order by stochastic (ie, random) cooling: identifying a wayward particle on one side of the accelerator ring, sending a signal directly across to the other end, and tweaking the magnetic field to nudge the oncoming errant particle back into the beam.
