由于带电粒子通过跟踪介质时产生的许多相关空间点，来自大型气体探测器的时间信号可能显示出动态标度。这一点已经通过使用欧洲核子研究中心爱丽丝对撞机实验中正在制造的时间投影室(TPC)的真实参数进行模拟来证明。这种动力学行为的一个有趣的方面是普遍标度的存在，它不依赖于碰撞的多重性。这方面可进一步用于在器件水平上研究物理，也可用于在线监测某些物理观测数据，包括电子噪声，这是实现最佳TPC性能的几个关键参数。
The temporal signals from a large gas detector may show dynamical scaling due to many correlated space points created by the charged particles while passing through the tracking medium. This has been demonstrated through simulation using realistic parameters of a Time Projection Chamber (TPC) being fabricated to be used in ALICE collider experiment at CERN. An interesting aspect of this dynamical behavior is the existence of an universal scaling which does not depend on the multiplicity of the collision. This aspect can be utilised further to study physics at the device level and also for the online monitoring of certain physical observables including electronics noise which are a few crucial parameters for the optimal TPC performance.
