Time-of-flight systems, based on scintillators, may reach good intrinsic time resolution, by using fast scintillators and photomultipliers. Examples are the large time-of-flight system constructed for the HARP experiment at CERN PS (~150 ps detector resolution) or the most demanding time-of-flight system of the MICE experiment at RAL (~50-60 ps detector resolution).
This level of intrinsic...

Modern detectors with significantly increasing number of active channels require new approach for calibration. The calibration system on the first prototype of the AHCAL in CALICE used one optical fibre for each of 7608 channels to distribute calibration light to tiles with SiPM. As the proposed analogue hadronic calorimeter for ILC should have around 10^6 channels, the former system is...

Future astroparticle physics facilities like CTA [1] and KM3NeT [2] require a relative timing precision better than 1 ns between detector elements separated by up to 100 km. At the same time, fiber-optical links for high-capacity data transfer from detector elements to central processing facilities are needed. The Open Hardware project White Rabbit [3] provides both data and time transfer...

We will report a study of the phase camera, which is a wave-front sensor of laser. This sensor is utilized for observing phase-modulated laser in an interferometer of gravitational wave (GW) detectors. The GW detectors are well sophisticated apparatus that need accurate position controls for mirrors. The laser modulation/demodulation is used for readout of the mirror displacement in such...

Physics experiments generally deal with enormous data throughput. The density of the data is increasing with upgrades on the detectors and experiments. Fiber optic communication with its high bandwidth and high capacity provides an effective solution. In experiments like the KM3NeT, cost-effective long haul optical communication is desired. A Dense Wavelength Division Multiplexed (DWDM) based...
