A thermal bonding method for manufacturing Micromegas detectors
نویسندگان
چکیده
For manufacturing Micromegas detectors, the “bulk” method based on photoetching, was successfully developed and widely used in nuclear particle physics experiments. However, complexity of requires a considerable number advanced instruments processing, limiting accessibility this for production detectors. In view these limitations with bulk method, new thermal bonding technique (TBM) has been to manufacture detectors much simplified efficient way without etching. This paper describes TBM detail presents performance built TBM. The effectiveness investigated by testing detector prototypes method. Both X-rays electron beams were characterize gas mixture argon CO2 (7%). A typical energy resolution ?16% (full width at half maximum, FWHM) an absolute gain greater than 104 obtained 5.9 keV X-rays. Detection efficiency 98% spatial ? 65?m achieved using 5 GeV beam DESY test-beam facility. could reach up 105 uniformity better 10% when size avalanche gap optimized thanks flexibility defining gap. Additionally, facilitates exploration structures owing much-simplified operation

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 کاملDeveloping a software for simulation of gaseous detectors with Monte carlo method in c++ programming language
In this paper we consider a gaseous detector and supposed, because of pass of an ionizing radiation, an electron created inside it. By numerical simulation with monte carlo method and concluding the impacts, scatterings and creation of secondary electrons, we find the trajectory of initial and secondary electrons. Dependence of number of secondary electrons to applied electrical field is invest...
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 ...
