Neutrons and X-rays are two of the most important probes in studies of
materials and physical phenomena. Throughout the world, major user
facilities with beams of ever-increasing intensity of both types of radiation
have been constructed or planned in recent years. This has created a need
for neutron and Xray detectors with greater sophistication and higher
counting rate capability....

The Time Pro jection Chamber (TPC) for the International Linear Collider
(ILC) will measure about 200 track points with a resolution close to 100 μm.
A Micro Pattern Gas Detector (MPGD) readout TPC may achieve the target
resolution with existing techniques using 1 mm or narrower pads at the
expense of increasing the detector cost and complexity. The new MPGD readout
technique of...

Time projection chamber (TPC) is considered as a strong candidate for the
central tracker at the future linear collider experiment because of its large
volume coverage and high three-dimensional granularity. Since the
performance of TPC depends on its readout scheme we have conducted a
series of experiments in order to compare the performance of prototype
TPCs equipped with different...

Since its introduction in 1996 GEM (Gas Electron Multiplier) has attracted a
lot of interest due to many promising features: good position accuracy and
two track resolution, high rate capability, high radiation tolerance and time
stability, large flexibility of the geometrical shapes and readout schemes.
This has led to a wide range of applications from simple tracking and
triggering...

For its physics program with a high-intensity hadron beam of 2·10 7
particles/s, the COMPASS experiment at CERN requires tracking of charged
particles scattered by very small angles with respect to the incident beam.
While good resolution in time and space is mandatory, the challenge is
imposed by the high beam intensity, requiring radiation hard detectors
which add very little...

The performances of two-phase Ar and Xe avalanche detectors were studied,
aiming at their potential application in low-background experiments, such as
those of coherent neutrino-nucleus scattering and dark matter search. The
two-phase avalanche detector had a liquid Ar or Xe layer and a triple-GEM
multiplier operated in the saturated vapour above the liquid phase. The suc-
cessful...

In recent years the detection of minimum ionising particles in a gaseous
detector by means of a CMOS pixel readout circuit as direct anode, has been
demonstrated. Sofar the used pixel circuitry provided only a 2-dimensional
projection of the position of the primary ionisation clusters. In the newly
developed TimePix chip, based on the earlier used Medipix2 chip, each pixel
also has...

Recently developed micropattern gaseous detectors open new avenues in the
detectors technology. However, due to the fine structure of their electrodes,
these detectors are quite fragile and can be damaged by sparks. We have
developed and successfully tested several prototypes of micropattern gaseous
detectors based on a new design in which the cathode or the anode (in some
case both...
