متن کاملTest of ATLAS RPCs Front-End electronics
The Front-End Electronics performing the ATLAS RPCs readout is a full custom 8 channels GaAs circuit, which integrates in a single die both the analog and digital signal processing. The die is bonded on the Front-End board which is completely closed inside the detector Faraday cage. About 50 000 FE boards are foreseen for the experiment. The complete functionality of the FE boards will be certi...
متن کاملA study of ageing in timing RPCs
The present study concerns the search for ageing effects in 0.3mm gap timing RPCs. Counters were made with glass and aluminium electrodes and kept under a continuous gas flow of tetrafluorethane with 10% sulphur hexafluoride, 5% isobutane and water at 10% relative humidity. After 500 days of operation at the saturation current an accumulated charge of 800mC was collected, equivalent to over 8 y...
متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
Latest Results on RPCs for the ATLAS LVL1 Muon Trigger
The performances of 3, 2 and 1.5 mm gap RPCs operated with a heavy, environmentally safe industrial gas, C 2 H 2 F 4 , have been tested at cosmic ray fluxes. Emphasis is given to the study of avalanche-to-streamer transition. ( 1998 Elsevier Science B.V. All rights reserved. Resistive Plate Chambers will be used as the LVL1 muon trigger detector in the barrel region (DgD(1) of the ATLAS experim...
