The Medipix2-Based Network for Measurement of Spectral Characteristics and Composition of Radiation in ATLAS Detector
Nucl. Instr. and Meth. A, Volume 607, Issue 1, Pages: 35-37, doi: 10.1016/j.nima.2009.03.104
The ATLAS detector is now installed at the CERN LHC and a precise evaluation of the radiation environment within and around the detector is required in order to understand the performance of the various detector systems and to predict their useful lifetime. Furthermore, validation of earlier Monte Carlo predictions about the radiation field in ATLAS is necessary. In particular, it is important to perform these measurements in the early phases of the LHC operation. Many other radiation measuring devices lack sensitivity to low doses, and usually do not provide information on the composition of the radiation during this low intensity period. A network of 15 ATLAS-MPX devices has been installed at various positions in the ATLAS detector. These devices are capable of providing quantitative real-time information on the fluxes and flux distributions of the main radiation types in the experiment, including slow and fast neutrons. The technical description of the ATLAS-MPX detector network is presented as well as the principles of the data analysis.
