Description
The KM3NeT collaboration aims at the construction of a neutrino
telescope with a volume of several cubic kilometres at the bottom of
the Mediterranean Sea. The telescope will consist in an array of
Digital Optical Modules (DOMs) that will detect the Cherenkov light
originated by the interaction of the neutrinos with the matter in the
proximity of the detector. In the present article it is presented the
read-out electronics of the DOM, composed of PMT bases, in charge of
converting the analogue signal produced in the 31 PMTs in a Low
Voltage Digital Signal (LVDS); the Octopus boards, that transfer the
LVDS signals from the PMT bases into the Central Logic Board (CLB);
the CLB, the most complex board of the read-out system, with 31 Time
to Digital Converters of 1 ns resolution and the White Rabbit protocol
embedded in the CLB Field Programmable Gate
Array, and the Power Board, that delivers all the power supplied need
by the DOM electronics. All the DOM read-out electronics system is
fully described in the present article.
