The KM3NeT neutrino telescope will be composed by tens of
thousands of glass
spheres (nodes) including each 31 of small photocathode
(3''). The readout and data
acquisition system of KM3NeT has to collect, treat and send
to shore, in an economic
way, the enormous amount of data produced by the
photomultipliers and at the
same time to provide time synchronization between each...

The KM3NeT-Italy Collaboration has entered the production
stage of an 8 tower
apparatus that will be deployed at about 100 km away from
the Sicily coast. The
architecture of the system is based on the NEMO Phase-2
prototype tower that is
taking data since the deployment in March 2013. In order to
optimize production
costs, power consumption, and usability some components
have...

Time to Digital Converters (TDCs) are a very common devices in particle physics
experiments. In the case of KM3NeT, thirty-one 1-ns resolution TDCs are used
in order to discretize the photomultiplier output. The TDC has been embedded
on a Field-Programmable Gate Array (FPGA). An architecture with low resources
occupancy has been used allowing the implementation of other...

In March 2013, the Nemo Phase II tower has been successfully installed
at Capo Passero, Italy, at 3500 m depth. The 8-floor tower hosts 32
10-inch PMTs. Results from the last 3-months background measurements
will be presented. In particular, the analyzed rates show stable and low
baseline values, compatible with the contribution of 40K light emission,
with a small percentage of...
