ORCA is operational

8 March 2019 – Last month, the KM3NeT team of CPPM, Marseille together with the ship crews successfully installed an ORCA detection unit. It was the first unit connected to the refurbished main electro-optical cable to shore. After a few weeks of technology tests, the unit is given free for physics runs. ORCA is operational!

ARCA is alive again

29 January 2019 – KM3NeT had a good start of 2019. Data taking of the first detection unit of ARCA could be resumed, after the operation of the unit had to be stopped in 2017, because of a fault in the seafloor cable network. Read more



Launch of ESCAPE cluster for Open Science

20 November 2018 – As an ESFRI research infrastructure for neutrino astronomy and particle physics, KM3NeT actively participates in the new ESCAPE science cluster that will address Open Science data challenges shared by the participating European large research infrastructures for astronomy and particle physics. Early 2019, ESCAPE will be launched officially. Read the press release and the project summary.

Characterisation of photomultipliers for KM3NeT

31 May 2018 – Each KM3NeT optical sensor module contains 31 photomultiplier tubes. Each KM3NeT detection unit comprises 18 optical modules, i.e. a total of 18 x 31 = 558 photomultipliers. Together the ARCA and ORCA detectors of KM3NeT will comprise a total of 345 detection units, i.e. 345 x 558 =192,510 photomultipliers. So, you can imagine that it is important to very well understand the characteristics of these photomultipliers. Read more
