The origin of cosmic rays has been a great mystery since they were
discovered by Victor Hess in 1912. The AGASA observation of ultra-high-
energy cosmic rays (UHECR) possibly beyond the GZK cutoff stimulated the
field a great deal. In addition, the Kamiokande detection of neutrinos from
SN1987A and the H.E.S.S. detection of TeV gamma-rays from supernova
remnants demonstrated the...

The ANTARES telescope is a device of a 0.1 km size to detect high energy
neutrinos. It is located in the Mediterranean Sea at a depth of 2500 meters.
It consists of a three-dimensional matrix of optical modules (OM) containing
photomultiplier tubes. As of September 2006 two complete lines and an
instrumentation line, called MILOM, are deployed and fully operational for
data taking....

The main task of the Target Tracker of the long baseline neutrino oscillation
OPERA experiment, is to locate in which of the target elementary
constituents, the lead/emulsion bricks, the neutrino interactions have
occurred and also give calorimetric information about each event. The
technology used consists in walls of two planes of long plastic scintillator
strips, one per...

The CALICE collaboration is presently constructing a test hadron calorimeter
(HCAL) with 8000 scintillator tiles read out by novel Geiger mode semicon-
ductor photo detectors - Silicon Photomultipliers (SiPMs). This prototype is
the first device which uses SiPMs on a large scale. We present the design of
the HCAL including scintillator tile - WLS fiber - SiPM systems, mechan-

Silicon photo-multipliers (SiPM) consist in matrices of tiny, passive quenched
avalanche photo-diodes connected in parallel and operated in Geiger mode.
Their capability to detect low optical photon fluxes with unprecedented
amplitude resolution and their extreme single photon timing resolution
make SiPM’s suitable for many applications. The DASIPM 1 collaboration
between the Italian...

The Multi Pixel Photon Counter is a novel semiconducting photon counting
device made by Hamamatsu Photonics K.K. based on concept of Silicon Pho-
tomultiplier. The MPPC consists of 100-1600 APD (avalanche photo-diode)
pixels, and each pixel works in limited Geiger mode with inverse bias voltage
around 80 volts, which is a few volts above breakdown voltage. The MPPC
has excellent...

The X-HPD concept is a modern implementation of the Dumand and Lake
Baikal approach to large area photon detectors, primarily aimed for water
based Cherenkov detectors. The main components are an almost spherical
vacuum tube of 8-inch diameter and a LYSO scintillation crystal mounted in
the centre of the tube. The scintillation light produced after the impact of a
photoelectron which...

The development of scintillation detectors to be used in a high magnetic field
environment requires novel photodetectors to substitute photomultiplier tubes
(PMTs). Avalanche microchannel photodiodes (AMPDs) are competitive to
PMTs in terms of gain and photon detection efficiency and insensitive to
magnetic fields. In this work we use AMPD arrays to build fast timing and
large area...
