A new Micromegas manufacturing technique, based on kapton etching technology, has been recently developped, improving the uniformity and stability of this kind of readouts. Excellent energy resolutions have been obtained, reaching a 11% FWHM for the 5.9 keV photon peak of 55Fe source and 1.8% FWHM for the 5.5 MeV alpha peak of the 241Am source. The new detector has other advantages like its...

The Microstrip Gas Chamber was the first micropattern detector used for thermal neutron detection. Several studies regarding the Gas Electron Multiplier (GEM) to neutron detection have been performed. High charge gains could not be achieved at high pressures, but the readout of the scintillation produced in the electron avalanches, using a CCD camera, allowed the development of GEM-based...

In this article we would like to present the study of the ageing properties of construction materials for the Multi Wire proportional Chamber (MWPC). This work is a part of the detector R&D of the CBM experiment at FAIR. CBM will use several gas detectors at high interaction rates. The construction materials for the production of the detectors have to be chosen properly in order to ensure the...

The energy-selective neutron radiography is a new field to study fine structure of heavy material using pulse neutron sources. In order to perform such radiography, two-dimensional position and precise temporal measurement are essential. Therefore, we are developing a gaseous neutron detector with a gas electron multiplier (GEM). For neutron detection, aluminum cathode surface is coated with...

In the last few years, considerable effort has been devoted to the development of gaseous photomultiplier tubes (PMTs) with micro-pattern gas detectors (MPGD) which are sensitive to visible light. The potential advantage of such a gaseous PMT is that it can achieve a very large effective area with moderate position and timing resolutions. Besides it can be easily operated under a very high...

The micromegas group working for CAST is devoting a substantial effort towards a deep understanding of the very low background levels observed in the detectors installed in the experiment which, since the implementation of shielding and the introduction of the microbulk technology, are as low as to ~5×10-6 keV-1s-1cm-2 in the axion energy range. A replica of the CAST set-up has been...

The Time Projection Chamber of the ALICE experiment has been operated
successfully since the CERN Large Hadron Collider started to provide collisions
in November 2009. More than 1 billion physics events have been read out from
the TPC with pp collisions (mainly at a center of mass energy of 7TeV), and
about 75 million with Pb-Pb collisions at 2.76TeV per nucleon pair (in
November 2010)....

We present work on the detection of neutral particles via nuclear recoils in gas-filled Time Projection Chambers (TPCs). We employ Gas Electron Multipliers (GEMs) to amplify the signal and silicon pixel electronics to read out the projected track. These technologies allow ionization in the target gas to be detected with low noise, improved position and time resolution, and high efficiency....

The Dark Matter Time Projection Chamber (DMTPC) experiment uses a time projection chamber filled with low pressure CF4 gas to detect the direction of WIMP-induced nuclear recoils. Recoils from WIMPs in the galactic dark matter halo are expected to have a directional signal distinct from all known backgrounds. Recent work has been done to develop instrumentation to read out both the...

The NA62 experiment at CERN, aiming at a precision measurement of the ultra-rare decay K+ -> pi+ nu nubar, relies on kinematical rejection up to 10^5 (~10^10 is needed in total). One of the limiting factors to achieve this goal is the multiple scattering in the magnetic spectrometer for kaon decay products; therefore an almost massless (~1.5% X0) straw tracker has been designed to operate in...

Operating and planned HEP experiments use and study large area gas-based detectors for charged particles.
For most such detectors the control of the gas temperature is of foremost importance because of the
very large dependance on the gas gain. Examples of detectors whose efficiency is particularly dependent on
temperature are Resistive Plate Counters (RPC) and Gas Electron Multipliers...

High resolution scanning system was used to locate the areas on GEM-foils that might contain short-circuit. These areas were analyzed by threshold method for fast identification. Different methods to remove short-circuits on GEM-foils were studied. Since using the standard procedure of “burning” shorts with high current might incur additional damage to the foil, we have also studied several...

Very large systems of RPCs with 2 mm gas gap are presently working at LHC as muon trigger detectors. In order to conceive a new generation of RPCs, fully adequate to the needs of the high luminosity super-colliders of the next future, two aspects have to be reconsidered: the gap width which determines the amount of charge delivered in the gas per detected avalanche and the front end...
