Para el público esto significa que la ciencia argentina del siglo XXI también se mide en instrumentos que se construyen y se prueban en condiciones extremas, lejos de la mirada cotidiana. El límite es que se trata de una validación técnica inicial: todavía falta demostrar la sensibilidad que se necesita para observar fuentes astrofísicas concretas.","quienFirma":"Colaboración KM3NeT","confianza":"revisado","consulta":null},"sello":{"hash":"a5f417e4598d92de6cfa65ca80edc4bdbf9eae735f59c4c8b09e80e30177c7c8","sello":"e9ad6e0c9b160360c76200ed3c7d02969c3af612677a2dbd6540c6df49c9ff17","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6576029,"aleatorio":"69283f2fd8851a8002724d67837843bb8976a4586c383157298d64ec1d5a13b2","tiempo":"2026-10-22T23:31:30.000Z"},"nist":{"cadena":2,"pulso":1995214,"salida":"70537C3225E32BF1087CE09A63B5B27ED328E3F6DCEBA086BA2A8C346D9A96196BB6F2563A9A354265AFE9D778A41AB61A1BEBBBBCE5474D3C95C4F9550715BF","tiempo":"2026-10-22T23:31:00.000Z"},"noAntes":"2026-10-22T23:31:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 23:32:11 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Deep sea tests of a prototype of the KM3NeT digital optical module","descripcion":"The first prototype of a photo-detection unit of the future KM3NeT neutrino telescope has been deployed in the deep waters of the Mediterranean Sea. This digital optical module has a novel design with a very large photocathode area segmented by the use of 31 three inch photomultiplier tubes. It has been integrated in the ANTARES detector for in-situ testing and validation. This paper reports on the first months of data taking and rate measurements. The analysis results highlight the capabilities of the new module design in terms of background suppression and signal recognition. The directionality of the optical module enables the recognition of multiple Cherenkov photons from the same $^{40}$K decay and the localization bioluminescent activity in the neighbourhood. The single unit can cleanly identify atmospheric muons and provide sensitivity to the muon arrival directions.","pubDate":"2026-10-19","url":"https://in2p3.hal.science/in2p3-00998515"},"indexado":"2026-10-22T23:31:13.379Z"}}
