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 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 ...
متن کاملMicromegas for imaging calorimetry
Gaseous detectors have been used in sampling calorimeters for several years and still remain an attractive option for future collider experiments. The use of Micromegas chambers as active elements of a hadronic calorimeter was proposed a few years ago and stirred up exciting developments of this technology. Basic building blocks of large size chambers acting as signal generating and processing ...
متن کاملPiggyback orthotopic intestinal transplantation.
PORTAL, as opposed to systemic, venous drainage from small intestinal allografts is thought to be preferable because it provides unquestionable physiologic (1-3) and hypothetic, but unverified (4,5) immunologic advantages. However, in clinical instances, it may be difficult to find a place on the recipient portal or superior mesenteric vein (SMV) where the donor portal vein can be anastomosed. ...
