论文摘要
电阻板室(RPC)在大型强子对撞机上表现出稳定的操作,并在整个运行1(2010-2013)和2(2015-2018)中具有令人满意的效率,并使用C $ _ {2} $ _ {2} $ _ {2} $ h $ _ {2} $ _ {2} $ f $ _ {4} $ _ {4} $ - 基于基于Sf $ _ _} i-c $ _ {4} $ h $ _ {10} $。由于其全球变暖潜力(GWP)很高,因此C $ _ {2} $ h $ _ {2} $ f $ _ {4} $由于最近的欧洲联盟法规而逐步淘汰生产,因此其成本逐渐增加。因此,找到具有低GWP的新RPC气体混合物已经变得非常重要。该贡献描述了用四氟丙烯C $ _ {3} $ h $ _ {2} $ f $ _ {4} $(HFO1234ZE),一种非常低的GWP的氢氟菌素。模拟结果与C $ _ {3} $ H $ _ {2} $ f $ _ {4} $ - 基于AR的添加AR,HE,CO $ $ _ {2} $ $ $ $ $ $ _ {2} $ _ {4}的$ _ {4} $ {4} $ {4} $ {4} $ {4} $ {4} $ {4} $ {4}的仿真结果。该模拟允许研究C $ _ {3} $ h $ _ {2} $ f $ _ {4} $与混合物中的其他气体组件之间的相互作用,并且可以允许识别与C $ _ {3} $ h $ _ $ _ $ _ for的最有希望的环境友好的气体混合物。
Resistive Plate Chambers (RPC) have shown stable operation at the Large Hadron Collider and satisfactory efficiency for the entire Run 1 (2010-2013) and Run 2 (2015-2018) with C$_{2}$H$_{2}$F$_{4}$-based gas mixtures and the addition of SF$_{6}$ and i-C$_{4}$H$_{10}$. Since its global warming potential (GWP) is high, C$_{2}$H$_{2}$F$_{4}$ is phasing out of production due to recent European Union regulations and as a result its cost is progressively increasing. Therefore, finding a new RPC gas mixture with a low GWP has become extremely important. This contribution describes the simulation of the RPC efficiency with tetrafluoropropene C$_{3}$H$_{2}$F$_{4}$ (HFO1234ze), a hydrofluoroolefin with very low GWP. Simulation results are systematically compared with measurements of RPC efficiency in C$_{3}$H$_{2}$F$_{4}$-based gas mixtures with the addition of different combinations of Ar, He, CO$_{2}$, O$_{2}$ and i-C$_{4}$H$_{10}$ in various concentrations. This simulation allows the study of the interplay between C$_{3}$H$_{2}$F$_{4}$ and the other gas components in the mixture as well as may allow the identification of the most promising environment-friendly gas mixtures with C$_{3}$H$_{2}$F$_{4}$ for RPCs.
