Gas mixtures for particle detectors are conventionally prepared using mass flow controllers, which can be costly. This work presents the development of a low-cost volume-based gas mixing system that uses peristaltic pumps to produce gas mixtures through volumetric dosing. The effectiveness of the system was evaluated using gas chromatography by comparing the composition of the produced mixture...

The CMS experiment is upgrading the muon system for High-Luminosity LHC (HL-LHC). Improved Resistive Plate Chambers (iRPCs) will be installed in the endcap stations RE3 and RE4. Compared to conventional RPCs, iRPC has better timing performance because it uses dual TDC channels with bunch-crossing, sub-bunch-crossing, and fine-time information, giving much finer time resolution than the 25 ns...

Resistive Plate Chambers (RPCs) traditionally operate with a gas mixture based on C$_2$H$_2$F$_4$ (TFE) and SF$_6$, both high-GWP greenhouse gases facing growing regulatory and supply restrictions. C$_3$H$_2$F$_4$ (F-HFO) diluted with CO$_2$ has been proposed as a lower-GWP substitute for TFE, while its chlorinated variant, C$_3$H$_2$ClF$_3$ (Cl-HFO), has separately been explored as a streamer...

Resistive Plate Chamber (RPC) detectors are widely used in major CERN experiments as muon trigger systems thanks to their excellent time resolution. However, the gas mixtures currently employed in RPCs contain greenhouse gases, such as C2H2F4 (R134a) and SF6, with Global Warming Potential (GWP) of 1430 and 22800 respectively, which contribute significantly to environmental emissions. During...

High energy collisions in LHC produce an enormous number of particles and consequently a large quantity of electronic signals, which is a challenge for the The Compact Muon Solenoid (CMS). The increasing instantaneous luminosity of the LHC, i.e. HL-LHC, will be in the order of 2 x 10^34 cm^(-2)s^(-1). In that context, the CMS Level-1 (L1) trigger system rapidly processes raw information of the...
