No full textMULTIWIRE DRIFT TUBES WITH JET-CELL GEOMETRY FOR MUON DETECTION AT LHC
No full textRecent results from test measurements with cosmic rays of jet-cell chamber prototypes, developed and studied for the mu, detector of the ATLAS apparatus, are reported
Performance and some characteristics of MDT chambers constructed in IHEP (Protvino) for ATLAS
No full textIHEP (Protvino) is responsible for construction of 60000 drift tubes and their assembling into 192 Monitored Drift Tube (MDT) chambers for two outer stations of the ATLAS Muon Spectrometer end-cap. More than 45000 tubes and 114 chambers have been assembled and tested up to now. The paper reports brief introduction of the chamber design and assembling technique. Measurements results of mechanical precision and some characteristics: precision of wire location, gas leak rate, cosmic counting rate, wire resolution - are presented. (12 refs)
Prototype tests of a ''jet cell'' drift chamber for large-area muon detection
No full textLarge-area, high-precision drift chambers, based on the "jet cell" concept, have been developed for the muon spectrometer of the ATLAS experiment at LHC. Emphasis is placed on the control and reduction of systematic error in the drift measurement and in the mechanical construction. Results of measurements on prototypes are given. These indicate that a global precision of σ ≲ 70 μm is achievable for large-area chambers
Construction of monitored drift tube chambers for ATLAS end-cap muon spectrometer at IHEP (Protvino)
No full textTrapezoidal-shaped Monitored Drift Tube (MDT) chambers will be used in end-caps of ATLAS muon spectrometer. Design and construction technology of such chambers in IHEP (Protvino) is presented. X-ray tomography results confirm desirable 20 mum precision of wire location in the chamber
