The aim of this work has been to investigate the performance of digital pulse shape analysis (PSA) [1] applied to improve the position resolution of EXOGAM [2] high purity Germanium (HPGe) clover detectors. Unlike arrays currently under development such as AGATA [3] and GRETA [4], EXOGAM was not designed for the implementation of PSA and as such is less suitable; however any improvement in...

The all-silicon design of the CMS Tracker poses new challenges in aligning the system with more than 15000 independent modules. For optimal track-parameter resolution, the position and orientation of its modules need to be determined with a precision of better than few dozens of micrometers. Starting with the survey measurements and corrections provided by the hardware alignment system, we can...

The Pixel Detector is a key component of the inner tracking detector of ATLAS, constructed to allow precision tracking of charged particles and vertexing. The ATLAS pixel detector system contains approximately 80 million channels and 1744 detector modules, has been already installed in its final position inside ATLAS and is ready for the first beams of the Large Hadron Collider at CERN. The...

Particle tracking detectors made on high resistivity (HR) float zone (FZ) silicon are widely used in high energy physics experiments. Results from the CERN RD48 and RD50 collaborations have shown that diffusion oxygenated FZ (DOFZ) silicon can better withstand the high hadron fluences expected for 10 years operation of the Large Hadron Collider at CERN. Recently, new semiconductor industry...

Delay-Line readout method is suitable for GEM detector in low-rate environment. According to the electric circuit model of delay-line and the output signal of GEM detector, we construct a full simulation model of delay-line readout system, containing delay-line readout PCB, Amplifier, Constant-fraction discriminator and Time-Digital converter. Three kinds of delay-lines, with the per cell time...

In this paper we would like to present a comparative study of the Resistive Plate Chambers (RPC) made of different grades of Bakelite paper laminates, produced and commercially available in India. The chambers, operated in the streamer mode using argon, tetrafluroethane and isobutene in 34:59:7 mixing ratio, are tested for the efficiency and stability with cosmic rays. A particular grade of...

Microstrip edgeless silicon detectors have been successfully produced and tested. These detectors are fabricated with standard planar technology, reach full sensitivity in 50 m from the cut edge and can operate with high bias at room temperature. These detectors employ a newly conceived terminating structure, which, although is extremely reduced with respect to the conventional ones, still...

We present a cosmic rack, the FinnCRack. This device is a silicon strip detector based telescope that measures tracks of cosmic particles. FinnCRack is constructed using components of the Tracker Outer Barrel (TOB) of the CMS experiment at the CERN LHC. The FinnCRack provides temperature and humidity control. The data is analyzed using the official CMS analysis software package, CMSSW. The...

Monolithic Active Pixel Sensors (MAPS) form a set of new detector technologies currently under study as possible vertex and tracking sensors to be used in future high energy physics (HEP) experiments. The most active research is being carried out as part of R&D for future e+e- colliders while such devices are also a possibility for vertexing at a neutrino factory near detector. Here presented...

Double-sided Double-Type Column 3D detectors (3D-DDTC) have been fabricated at Fondazione Bruno Kessler (former IRST). These sensors have columnar electrodes etched perpendicularly to the wafer surface from both sides and not fully penetrating into the substrate, so that the fabrication process is simpler than for standard 3D detectors. Compared to the previously developed 3D...

A new type of positron spectrometer for the MEG experiment has been developed at the Paul Scherrer Institute (PSI). The main goal of the experiment is a search for a lepton flavor violating decay mu+ → e+ gamma with a sensitivity of 10**-13 in branching ratio in order to check the predictions of the supersymmetric extensions of the standard model. Measurements of the reactions beyond the...

The P326 proposal of a new experiment NA62 aiming to perform precise measurement of the very rare kaon decay $K^+ \to \pi^+ \nu \bar{\nu}$ branching ratio at CERN is described. About 80 $K^+ \to \pi^+ \nu \bar{\nu}$ events with 10% of background is planned to obtain in two years of data taking. To reconstruct charged pion tracks with high efficiency and high resolution a single magnet...

Hybrid pixel detectors which will be operated in experiments after the luminosity upgrade of LHC, have to survive very high radiation doses up to $10^{16}~$1~MeV n$_{eq}$ per cm$^2$. Therefore, new sensor concepts exceeding the radiation tolerance of the currently used DOFZ planar n-in-n silicon sensors are under investigation. Among them are 3D active edge silicon detectors, single crystal or...

For the luminosity upgrade of the LHC, CMS is starting ambitious and diversified sensor research and development projects. The increased particle fluence implies more stringent requirements on the radiation hardness; the increased occupancy requires higher granularity; the need of moderating the material budget while increasing the number of readout channels suggests the use of thinner...

MICE (Muon Ionization Cooling Experiment) and its goal to demonstrate the feasibility of ionization cooling represent the first step towards a neutrino factory. Muons in MICE are produced by pions which derive from the interaction of protons with a target. Being muons short lived particles, a special cooling procedure has to be developed, able to reduce quickly the emittance. MICE intends to...
