So these monopoles could well turn up in our particle acceleratorsor in the decay products of cosmic ray collisions in the upper atmosphere.

所以这些单极在粒子加速器里或者在高空大气宇宙射线的碰撞过程中可能会被找到。

In recent years, scientists have been scaling up the power of the X-ray, using massive particle accelerators or synchrotrons to deliver much larger radiation doses.

近年来，科学家们利用大量的粒子加速器或者同步加速器来产生更大的辐射剂量，从而不断地提升X光射线的能量。

Two new looks at the gamma-ray sky suggest that if the mysterious matter is a particle, it is heavier than 40 gigaelectronvolts, about 44 times the mass of a proton.

两项最新伽马射线天空图的观测研究表明如果此种神秘物质是粒子，则要大约是一个质子质量的44倍，比400亿电子伏还重。

Although the probe would carry no cameras in the classic sense, its onboard instruments would include a low-energy charged particle experiment, a magnetometer, a cosmic ray detector, and an energetic neutral atom detector.
