Abstract
The phase-out of hydro-fluorocarbons, due to their high Global Warming Potential (GWP), affecting the main gas used in Resistive Plate Chambers (RPCs), tetrafluoroethane C_2H_2F_4, has increased pressure on existing systems and imposes strong restrictions on its use in new systems. A possible solution to the problem is the substitution of this gas by others with a much lower GWP. Another possibility would be sealed RPCs, i.e., RPCs that do not require a continuous gas flow for their operation. This paper shows the construction structure and test results of a sealed multi-gap RPC operated without gas flow for about 1 year. The results show a stable efficiency of more than 95% and a streamer percentage of less than 1%. The spatial distribution of the hits, the mean charge and the probability of streamers do not reveal significant structures. Similarly, they do not seem to be dependent on operating time.
