Characterization and Calibration of Large Area Resistive Strip Micromegas Detectors
Resistive strip Micromegas detectors have been tested extensively as small detectors of about 10 x 10 cm2 in size and they work reliably at high rates of 100 kHz/cm2 and above. Tracking resolution well below 100μm has been observed for 100 GeV muons and pions. Micromegas detectors are meanwhile proposed as large area muon precision trackers of 2-3 m2 in size. To investigate possible differences...
متن کاملMeasurements of spatial resolution of ATLAS Pixel detectors
Standard as well as irradiated silicon pixel detectors developed for the ATLAS experiment were tested in a beam. Digital and analog resolutions were determined comparing the positions measured by a microstrip telescope and by the pixel detector. Digital resolutions of 10 μm and analog resolutions of 6 μm (before irradiation) and 10 μm (after irradiation) are obtained without subtracting the err...
متن کاملSpatial Resolution Measurements of Gallium Arsenide Microstrip Detectors
Results are reported from beam test measurements of one of the first commercial prototype gallium arsenide microstrip detectors. The detector consisted of 128 strips on a 50μm pitch, with a wafer thickness of 200μm. Operating at a bias of 180V, the detector produced a signal to noise ratio of 19 to 1, with a particle detection efficiency of better than 99%. The spatial resolution of the detecto...
متن کاملmicrOMEGAs: Version 1.3
We present the latest version of micrOMEGAs, a code that calculates the relic density of the lightest supersymmetric particle (LSP) in the minimal supersymmetric standard model (MSSM). All tree-level processes for the annihilation of the LSP are included as well as all possible coannihilation processes with neutralinos, charginos, sleptons, squarks and gluinos. The crosssections extracted from ...
متن کاملMICROMEGAS: results and prospects
A lot of effort has been invested in the development of the Microstrip Gas Chamber (MSGC) [2] in order to be used as tracker for the LHC project. This technique allows good localization accuracy and double track resolution. However, it is necessary to operate it with a relatively low gas gain because of the presence of the insulator near the amplification region and because of the fragility of ...
