Performance of the NOMAD transition radiation detector

Calibration of the ALICE Transition Radiation Detector

The Transition Radiation Detector (TRD) belongs to the central barrel detectors of the ALICE experiment at the LHC at CERN. It is composed of 540 large area drift chambers, with a total of 1181952 readout pads (1728 or 2304 per chamber). To ensure the optimal performance of the detector, designed for electron/pion identification and charged particle tracking, including triggering for high-pt el...

Design and performance in the first flight of the transition radiation detector and charge detector of the CREAM balloon instrument

The Cosmic Ray Energetics And Mass (CREAM) instrument flew on a high altitude balloon in Antarctica in 2004–2005 for a record breaking 42 days. An array of detectors was deployed to identify cosmic rays and measure their energies up to several hundred TeV. A major science goal is the measurement of secondary nuclei at high energy (produced by spallation reactions of heavier cosmic rays in the i...

First Look at Neutrino Interactions in the Nomad Detector

The Nomad experiment, currently taking data at the CERN SPS, is searching for to oscillations. The maximal sensitivity is obtained for m 2 > 20 eV 2. In this region the current limit on the mixing angle can be improved by an order of magnitude if no evidence for oscillations is found. Some sensitivity to mixing is retained down to 1 eV 2. The detector was completed during the 1995 data taking p...

the effects of time planning and task complexity on accuracy of narrative task performance

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
