摘要

CMS实验中电阻板室（RPC）系统的当前操作涉及大约95%的四氟乙烷（C2H2F4， TFE）。然而，为了应对气候变化问题，由于TFE的全球变暖潜势升高，欧盟已经制定了一项禁令，导致市场价格相应上涨。在此框架下，RPC EcoGas@GIF++协作中共同努力，致力于研究基于四氟丙烯（C3H2F4, HFO-1234ze）的新型生态气体混合物，以确保RPC的可持续功能。这一贡献将深入研究在HFO/ co2基混合物上运行的改进RPC气隙作为生态可行替代品的性能结果，特别是在高亮度LHC阶段（HL-LHC）的预期中。

However, in response to climate change concerns, the European Union has instituted a ban on TFE owing to its elevated Global Warming Potential, resulting in an associated increase in market prices. In this framework, shared endeavors within the RPC EcoGas@GIF++ Collaboration, have been dedicated to investigating novel ecological gaseous mixtures based on tetrafluoropropene (C

期刊介绍： Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section. Theoretical as well as experimental papers are accepted.
