In perspective of an upgrade of the CMS Experiment, the GEM for CMS collaboration is performing feasibility studies on employing Triple-GEM detectors for the high-eta region (1.6-2.4) of the CMS Endcap, which is currently not instrumented. A detailed review of the development and characterization of the CMS full-size prototypes baseline detector will be presented. GEMs have excellent spatial...

Driven by the availability of modern photolithographic techniques, the RD51 collaboration is developing a variety of new Micro Pattern Gas Detectors (MPGD). Developments cover Gas Electron Multipliers (GEM) and Micromegas, thick-GEM, resistive GEM (RETGEM) and novel micro-pattern devices like GridPix. The aims of the collaboration are to facilitate the development of these advanced...

Neutrinoless double beta decay is a hypothetical, very rare nuclear transition in which two neutrons undergo beta decay simultaneously and without the emission of neutrinos. The importance of this process goes beyond its intrinsic interest: an unambiguous observation would establish a Majorana nature for the neutrino and prove the violation of lepton number.
NEXT is a proposed 100-kg...

Many experiments in particle physics employ Micropattern Gas Detectors (MPGDs) in combination with pads or stripes with a typical size of several square mm. With a pixelized readout structure the performance can be improved, as the size of the gas amplification stage is matched by the granularity of the readout.
GridPix detectors are pixel chips with an integrated Micromegas structure,...

We are developing a new concept of gamma-ray telescope above
pair-creation threshold, with an angular resolution improved by one
order of magnitude wrt Fermi / EGRET, polarisation sensitivity, and an
effective area of several squared meters/ton.
Improving the angular resolution is the key factor to lowering the
sensitivity limit for point-like faint sources and fill the
"sensitivity...

A large TPC has been selected as one of two options for the main tracking at the Linear Collider. The LCTPC Collaboration has been conducting R&D in various directions for over 10 years. As a starting point, a Large Prototype consisting of a 72 cm diameter, 60 cm long field cage and an endplate with 7 windows capable of hosting 7 identical detection modules has been built and is operational...
