The upgrade of the KLOE detector at the DAFNE Phi-factory foresees the insertion of a new Inner Tracker device around the interaction region, composed by four tracking layers with diameters from 260 mm to 410 mm and an active length of 700 mm. Each layer is realized as a cylindrical triple-GEM detector, a solution that allows to keep the total material budget under 2% of X0, of utmost...
49. Development of a new generation of micropattern gaseous detectors for high energy physics, astrophysics and medical applications
Prof. Vladimir Peskov (CERN)
2/12/13, 2:25 PM
During the last two years, our team has developed a cost effective technology of manufacturing various types of micropattern gaseous detectors designed for applications in many fields. The designs of these detectors feature a matrix of thin metallic readout strip located under segmented resistive electrodes. This electrode configuration makes such detectors very robust, allows them to be...

Resistive-anode Micromegas detectors are in development since several years, in an effort to solve the problem of sparks when working in high flux and high radiations environment like in the HL-LHC (ten times the luminosity of the LHC). They have been chosen as one of the technologies that will be part of the ATLAS New Small Wheel project (forward muon system). An ageing study is mandatory to...

Significant R&D on detectors for the future International Linear Collider (ILC) has been carried out by the community in the last decade. The International Large Detector (ILD) is one detector concept at the ILC where calorimetry and tracking systems are combined. The tracking system consists of a vertex detector and a large volume Time Projection Chamber (TPC). Within the framework of...
249. Measurements of the Gain, Time Resolution, and Spatial Resolution of a 20x20cm MCP-based Picosecond Photo-Detector
Dr Andrey Elagin (University of Chicago)

Microchannel plates (MCPs) allow for micron-level spatial imaging and picosecond-level time resolution, making them a good solution for the next generation of photo-detectors aiming for precision time-of-flight measurements. The Large-Area Picosecond Photo-Detector Collaboration (LAPPD) is currently developing a 20x20cm, thin, planar, glass-body detector with the MCPs serving as the gain...

The ATLAS Transition Radiation Tracker (TRT) is the outermost of the three tracking subsystems of the ATLAS Inner Detector The ATLAS detector is located at LHC/CERN. We report on how these gaseous detectors (“straw tubes”) are performing during the ATLAS 2011 and 2012 runs where the TRT experiences higher rates than previously encountered. The TRT contains ~300000 thin-walled...

A TRD prototype based on a single multiwire proportional chamber coupled with a small drift region was developed for the most inner part of the CBM-TRD subdetector. It preserves the same gas thickness for transition radiation absorption as the small size double-sided prototype for which an extrapolated pion efficiency of ~1% for a six layers configuration was obtained and fulfills the...

The innovative GridPix detector is a micro TPC, read out with a Timepix pixelchip. Each individual element of the 256x256 pixel-matrix is connected to a preamplifier, discriminator and TDC (100MHz) for time of arrival measurements. By using wafer post processing techniques an aluminium grid is placed on top of the chip. When operated, the electric field in between the grid and the chip is...
