The NUCLEON space experiment has been proposed to perform direct measurements of CR energy spectrum and composition up to E ∼ 10 eV. The NUCLEON detector consists of layers of different detectors: scintillator detectors with WLS fibers and silicon pad and microstrip ones. The results of beam and space qualification tests of the scintillator detectors are presented.
The possibility to enhance the capability of ATLAS Tile Calorimeter to identify low pT muons inside b-jets by the use of artificial neural networks technique is investigated in a systematic way on the basis of 2000 simulated jets.
Advantages of artiicial neural networks techniques in handling data from highly granulated ATLAS hadron calorimeter are shown in application to isolated == separation task in the range 3 < p T < 5 GeV at pseudorapidity = 0:3. Such low p T muons have a signiicant probability to be absorbed in the calorimeter and therefore they cannot be reliably registered by the muon detector. JETNET program was used to investigate the performance of neural network classiiers in solving low p T == separation task. Data sets for training and analysis were obtained with ATLAS simulation programs.
