Relativistic Range相对论范围
The ability to detect a short-lived particle depends upon it having enough range in the accelerator to reach the detector. This is a serious problem with particles which may have an average lifetime as short at 10-16 seconds! Even traveling at the speed of light, it will traveled only 0.03 micrometers before decaying, on average. The practical detection of short-lived particles depends upon relativistic time dilation. 检测短寿命粒子的能力取决于它在加速器中有足够的范围到达探测器。这在粒子平均寿命仅为10⁻¹⁶秒时是一个严重的问题!即使以光速运动,它平均也只能在0.03微米内衰变。短寿命粒子的实用检测依赖于相对论性时间膨胀。
![]() Because the clocks of the high speed particles run more slowly than the laboratory frame, the particles have a longer range in the accelerator than a non-relativistic treatment would anticipate. The numbers in the above illustration can be verified in the calculation below. 由于高速粒子的钟比实验室框架运行得更慢,因此在加速器中这些粒子的射程比非相对论性处理所预期的要长。上述示意图中的数字可以在下面的计算中得到验证。
Note: Muon parameters will be entered by default. All values may be changed. 注意:Muon参数将默认输入。所有值均可更改。
An example requiring the relativistic range to explain the observed data is the muon flux at the Earth's surface. 需要相对论范围来解释观测数据的例子是地球表面的μ子通量。
