is now fully dismantled...
June 23rd, 2022]
of the interlink cables between the junction box and
the line anchors, carried out with the manned Nautile
submarine on 12/02/2022, defined the end of data taking of
the ANTARES detector.
As a natural follow-up step, two dismantling campaigns took
place in May and June 2022. The Castor02 ship from Foselev
Marine and the Janus-II ship with its ROV Apache from SAAS -
the work horses used for the majority of ANTARES and
KM3Net/ORCA campaigns - had been in operation. During these
two operations all active detector elements have been
recovered and brought to shore. Only the junction box will
remain in place until a forthcoming KM3NeT campaign to
reroute the main electro-optical cable from the ANTARES to
the KM3NeT/ORCA site.
One of the last recovered elements was the PPM-DOM (see
Figure below), the first prototype of the future KM3NeT
DOMs, installed in 2013 and still in good shape. Some of the
ANTARES equipment, notably the optical modules with their
photomultipliers, might be used in future science projects.
Other parts will be recycled or used in exhibitions or other
outreach projects to illustrate the success of this
first-generation deep-sea neutrino telescope.
The recovery of
the PPM-DOM, the first prototype of the future
KM3NeT DOMs, still in good shape.
This marks the passage to the next generation -
ANTARES is now history,
long live KM3NeT !
