论文摘要
气态探测器被广泛用于高能物理实验中，尤其是在CERN大型强子对撞机（LHC）中，可在大容量上提供跟踪和触发。最近据估计，用于MUON检测的电阻板腔（RPC）对LHC实验的总温室气体（GHG）排放的贡献最高。 RPC的气体混合物主要由C $ _ {2} $ H $ _ {2} $ f $ _ {4} $制成，这是一种温室气体，对大气中的环境影响很高。 c $ _ {2} $ h $ _ {2} $ f $ _ {4} $由于最近的欧洲联盟（EU）法规，已经逐步淘汰生产，并且预计其成本在不久的将来会增加。因此，寻找由具有低全球变暖潜力（GWP）的气体组件制成的替代气体混合物对于限制温室气体排放以及出于经济原因而变得极为重要。 小说的Hydrofluoroolefins可能是适当的候选者，可以替换C $ _ {2} $ H $ _ {2} $ f $ _ {4} $由于它们的类似化学结构。这项研究的重点是用Tetrafropene HFO1234ZE（E）（C $ _ {3} $ H $ _ {2} $ f $ _ {4} $）的创新气体混合物的表征，这是最环保的Hydrofluoroolooloolefins之一，感谢其非常低的gwp。 HFO1234ZE（e）的加油混合物以及添加Ar，N $ _ {2} $，O $ _ {2} $和CO $ _ {2} $在本文中进行了广泛讨论，以及I-C $ _ {4} $ H $ _ $ _ $ _ {10} $ _ {10} $ _ {4} $ _ {10} $的角色。
Gaseous detectors are widely used in high-energy physics experiments, and in particular at the CERN Large Hadron Collider (LHC), to provide tracking and triggering over large volumes. It has been recently estimated that Resistive Plate Chambers (RPC), used for muon detection, have the highest contribution on the overall greenhouse gas (GHG) emissions at the LHC experiments. Gas mixtures for RPCs are mainly made of C$_{2}$H$_{2}$F$_{4}$, which is a greenhouse gas with a high environmental impact in the atmosphere. C$_{2}$H$_{2}$F$_{4}$ is already phasing out of production, due to recent European Union (EU) regulations, and its cost is expected to increase in the near future. Therefore, finding alternative gas mixtures made of gas components with a low Global Warming Potential (GWP) has become extremely important for limiting the GHG emissions as well as for economic reasons. The novel hydrofluoroolefins are likely appropriate candidates to replace C$_{2}$H$_{2}$F$_{4}$ due to their similar chemical structures. This study is focused on the characterization of innovative gas mixtures with tetrafluoropropene HFO1234ze(E) (C$_{3}$H$_{2}$F$_{4}$) that is one of the most eco-friendly hydrofluoroolefins, thanks to its very low GWP. HFO1234ze(E)-based gas mixtures with the addition of Ar, N$_{2}$, O$_{2}$ and CO$_{2}$ are extensively discussed in this paper as well as the role of i-C$_{4}$H$_{10}$ and SF$_{6}$ in such mixtures.
