KM3NeT - ORCA

First day of activity at the ORCA site

19 November 2021 – The first day of activity has gone at the ORCA site. Most efforts today were aimed at getting everything well prepared for the action. The first detection unit was then deployed to the sea bottom, precisely placed on the sea floor and connected to the submarine infrastructure. The tests performed from shore confirm that the dection unit is nicely working, and it now awaits to be “unfurled” to its work configuration. Deployment of the second detection unit has been started in the evening.

Yet another virtual spring meeting

A few weeks ago, KM3NeT held its two-week long spring meeting, once again virtually, like almost all meetings nowadays.

New publication: Neutrino Mass Ordering and Oscillation Parameters

05 May 2021 – The potential of KM3NeT to measure key properties of neutrinos – in March 2021, the KM3NeT Collaboration released a publication showing that KM3NeT with its ORCA detector will be in an excellent position to study the phenomenon of neutrino oscillations!

Data taking with KM3NeT

19 August 2019 – Since this spring, the KM3NeT telescopes are routinely operating with five detection units: four at the ORCA site, one at the ARCA site. First data results have been reported on the international conferences and workshops. Read more

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! Read more

The KM3NeT/ORCA neutrino detector is coming online

On 22 September 2017, after a two day long sea operation, the first detection unit of the ORCA neutrino telescope came online. This marks an important milestone of the scientific and technological endeavour of the international KM3NeT Collaboration.
