Computing and Data
The IceCube Neutrino Observatory is a cubic kilometer-scale neutrino
detector and air shower array at the geographic South Pole. The online
computing system for IceCube comprises subsystems for data acquisition (DAQ),
online filtering, supernova detection, and experiment control and monitoring. We
present the DAQ software and describe the process of forming events from
the stream of...

Computing and Data
In phase 2 of the NEMO neutrino telescope project a tower holding 32 optical
modules is operated since march 2013. A new, scalable Trigger and Data
Acquisition System (TriDAS) has been developed and extensively tested with the
data from this tower. Adopting the "all data to shore" approach, the NEMO
TriDAS is optimized to deal with a continuous data-stream from off-shore to on-
shore...

Computing and Data
The IceCube Neutrino Observatory was mainly designed to detect highly energetic neutrinos with its lattice of
5160 photomultiplier tubes monitoring 1 cubic kilometer of clear Antarctic ice. Due to low photomultiplier dark
noise rates in the cold and inert ice, IceCube is also able to detect several-second-long bursts of O(10 MeV)
neutrinos expected to be emitted from galactic core...

We studied a new trigger for NEMO Phase 2 tower based on hit time difference distribution. Such a trigger uses only a
fixed number of PMT signals in a time windows less than a maximum value. The background rate is drastically
reduced requiring hits from different PMT and a 75% trigger efficiency was estimated by a Monte Carlo simulation. The
trigger rate was also measured on raw data....

Computing and Data
The choice of using a relational database in the KM3NeT Collaboration has been
natural after the experience in the ANTARES experiment, but with a broader horizon.
The core of the system is a RAC installation hosted at the computing centre of IN2P3
in Lyon, but a geographically distributed DB network is foreseen. The DB is used for
Collaboration management, detector construction and...
