168. Gaseous Detectors R&D, where do we stand / where do we go

Eraldo Oliveri (CERN)

Rather than focusing on any specific research or technology, this contribution will emphasize the importance of collaborative efforts in advancing R&D in gaseous detector instrumentation.

It begins by contextualizing the setting up of several new R&D collaborations on instrumentation, specifically the newly established DRDs, following the recommendations from the latest European Strategy...

10. New RPC Gas Mixtures for Sustainable Operation in the CMS Experiment

Dayron Ramos Lopez (Universita e INFN, Bari (IT))

The current operation of the Resistive Plate Chamber (RPC) system within the CMS experiment involves approximately 95% tetrafluoroethane (C2H2F4, TFE). However, in response to climate change concerns, the European Union has instituted a ban on TFE owing to its elevated Global Warming Potential (GWP), resulting in an associated increase in market prices. In this framework, shared endeavors...

57. Signal shape studies and rate dependence of HFO-based gas mixtures in RPC detectors

Luca Quaglia (Universita e INFN Torino (IT))

The RPCs employed at the LHC experiments are currently operated in avalanche mode, with a mixture containing a large fraction of C2H2F4 (> 90%) with the addition of i-C4H10 and SF6 in slightly different concentrations (depending on the experiments). However, C2H2F4 and SF6 are fluorinated greenhouse gases (F-gases) with GWP of ~1400 and ~22800 respectively. EU regulations imposed a progressive...

162. Characterization of Glass Multigap RPC Detector with alternative gas to R134a and SF6

Glass Multigap Resistive Plate Chamber (MRPC) detectors are primarily used for their excellent time resolution properties in High Energy Physics and Tomography application. Typically, they are operated with a freon-based gas mixture containing C2H2F4 (R134a) and SF6, both greenhouse gases (GHG) with high global warming potential.

This study focuses on the construction and characterization...

58. Study of environment-friendly SF6 substitute for the Resistive Plate Chambers

Giorgia Proto (Max Planck Society (DE))

The standard gas mixture for the Resistive Plate Chambers (RPC), composed of $\rm{C_{2}H_{2}F_{4}}$/i-$\rm{C_{4}H_{10}/SF_{6}}$, allows the detector operation in avalanche mode, as required by the high-luminosity collider experiments. The gas density, the low current and the comfortable avalanche-streamer separation guarantee high detection efficiency, rate capability and slow detector...

52. R134a recuperation and SF6 recuperation plants: status and plan

Roberto Guida (CERN)

11/09/2024, 10:50

Particle detectors at the LHC experiments are very often characterized by large detector volumes and by the need of using very specific gases. Since the early phase, the gas consumption optimization was one of the design criteria. CERN is today strongly committed to reduce GHGs emissions from particle detector operation. In addition, GHGs are now subject to a phase down policy in Europe that...
