And yet an other boost for KM3NeT. Important upgrade of the deep-sea infrastructure of KM3NeT- It.

20 Jul 2015: In the morning of 20th July 2015, an important upgrade of the deep-sea infrastructure of KM3NeT-It was successfully concluded. During a sea campaign that started three days earlier the old termination frame at the deep sea end of the 100 km long main cable to shore was replaced by a new one and two junction boxes were installed.This major upgrade of the seafloor network at a depth of 3500 m was necessary to allow for the installation of a large number of detection units of the KM3NeT telescope. The first detection units are expected to be connected to the new junction boxes later this year.

Interested to join KM3NeT? The Collaboration invites new members.

23 May 2015: The KM3NeT Collaboration invites interested scientists to join the effort of building and operating the new generation neutrino telescope in the deep seas of the Mediterranean. Currently, the Collaboration is constructing the first phase of the detector. In the KM3NeT-Strategy Report 2015-05-06 you can read about the plans of the Collaboration for the next step, i.e. realising the high-energy ARCA detector at the KM3NeT-It site and the low-energy ORCA detector at the KM3NeT-Fr site.

Again an important step for KM3NeT. First seafloor network node of KM3NeT-Fr installed.

KM3NeT-Fr: Deployment of the node in the darkness of the early morning.27 Apr 2015: In the early morning of 27th April 2015, the first node of the seafloor network at the KM3NeT-Fr site was successfully installed. This is again an important step in the realisation of the KM3NeT neutrino telescope. During this April campaign, the node was connected to the 40 km long electro-optical cable which connects the network to the shore station. This cable was already deployed during the December campaign of last year.The heart of the node is an egg-shaped titanium vessel with electronics and photonics and sufficient sockets to plug in the cables coming from the many detection units to be anchored on the seabed. The first detection unit is expected to be connected later this year. More about KM3NeT-Fr…

KM3NeT-Fr. Cable comes to shore.

KM3NeT-Fr: Laying the MEOC toward the powerhut at the beach23 Dec 2014: In December 2014, for KM3NeT-Fr near Toulon, the Main Electro-Optical Cable (MEOC) connecting the deep-sea infrastructure with the shore was deployed. This is a major step in the construction of the KM3NeT-Fr installation site. The main cable lands in a power station at the beach of Les Sablettes, La Seyene sur Mer in the South of France. From there a land cable station with the control room of the shore station where the signals from the deep sea are collected, processed and submitted further over the internet to the central data repository in the computer centre in Lyon, France.

KM3NeT Strategy Document. Phased implementation of the KM3NeT Research Infrastructure.

KM3NeT2.026 November 2014:  The KM3NeT Collaboration has published its strategy for a phased construction of the KM3NeT Research Infrastructure at three locations in the deep seas of the Mediterranean at the southern coasts of Europe. The first phase of construction has started with furbishing the KM3NeT-Fr and KM3NeT-It locations with both deep-sea and on-shore infrastructures to host several hundredths of optical sensors of the neutrino telescope and two nodes for connection of instrumentation for earth and sea science research.Final phase of implementation of the research infrastructure include the extension of the neutrino detector to its full size of more than 12,800 sensors for the detection of cosmic neutrinos, the installation of a third node for earth and sea science research at the KM3NeT-Gr location and a neutrino detector dedicated to particle physics research at the KM3NeT-Fr location.As an intermediate phase, KM3NeT 2.0 is planned with an high-energy detector at KM3NeT-It and a low energy detector at KM3NeT-Fr.Read more in the KM3NeT-Strategy Report 2015-05-06

Detectors active at two different sites in the Mediterranean. First KM3NeT detection unit operational in the deep sea.

KM3NeT in the deep ea - Launcher of Optical Modules07 May 2014: The first KM3NeT detection was put into operation at the KM3NeT-It installation site, 100 km off the coast of the South East of Sicily, at a depth of 3500 m. Since more than a year, the first KM3NeT optical module is already operational inside the ANTARES telescope, situated close to the KM3NeT-Fr installation site, 40 km south of Toulon at a depth of 2400 m. With the successful completion of these two important technological steps at two different installation sites, the realisation of the first phase of the distributed KM3NeT neutrino telescope is well on its way. KM3NeT-Press release 2014-05-11
