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\u00a0year. 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.<\/jats:p>","DOI":"10.1140\/epjp\/s13360-023-04647-1","type":"journal-article","created":{"date-parts":[[2023,11,16]],"date-time":"2023-11-16T14:01:34Z","timestamp":1700143294000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Sealed (zero gas flow) resistive plate chambers"],"prefix":"10.1140","volume":"138","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9827-8294","authenticated-orcid":false,"given":"Alberto","family":"Blanco","sequence":"first","affiliation":[]},{"given":"Paulo","family":"Fonte","sequence":"additional","affiliation":[]},{"given":"Luis","family":"Lopes","sequence":"additional","affiliation":[]},{"given":"Mario","family":"Pimenta","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2023,11,16]]},"reference":[{"issue":"08","key":"4647_CR1","doi-asserted-by":"publisher","first-page":"08003","DOI":"10.1088\/1748-0221\/8\/08\/t08003","volume":"8","author":"M Capeans","year":"2013","unstructured":"M.
