Pierre Auger Observatory Located in the Pampa Amarilla, it is the largest observatory in the world dedicated to the study of Ultra High Energy Cosmic Rays (UHECRs) The main array is composed by more that 1600 water Cherenkov detectors which are overlooked by 4 Fluorescence Detectors The study of UHECRs allows not only to understand the nature and acceleration mechanisms of the most energetic known particles but also can be used to probe hadronic interaction above LHC energies
Auger: Develop an RPC - a gaseous particle detector In Auger we use RPCs to detect muons. We have a small test one to be built. Several solutions can be tested in this system. It will be the base component of a precision telescope. Period: 2 months, June-September Contact: Pedro Assis pedjor@lip.pt
Muon Tomography Cosmic ray muons are deeply penetrating particles. Muon telescopes can form images of the interior of mines, vulcanos, builidings, and even the nuclear reactors and cargo containers Producing and analysing muon tomographic images. Period: 2 months, June-September Contact: Lorenzo Cazon, Sofia Andringa cazon@lip.pt
Monitorização de LabRC: muões Desenvolvimento de um display de taxas de muões atmosféricos Os muões são partículas criadas na interação dos raios cósmicos com a atmosfera. No Laboratório de Raios Cósmicos existem detectores de cintilação capazes de detectar estas partículas. As taxas de muões detectadas na Terra apresentam variações de várias ordens (diárias e sazonais). Correlações com observações meteorológicas: http://meteo.tecnico.ulisboa.pt/obs/live Variabilidade temporal nas taxas de muões atmosféricos
Detector cintilador LabRC: Desenvolvimento de um display de taxas de muões O que se propõe neste trabalho é o desenvolvimento de software que permita monitorar em permanência a chegada de muões à Terra. Para isso será necessário calcular a sua taxa de deteção, e construir de seguida um gráfico (display) que permita Leitura Remota mostrar a taxa ao longo do tempo num ecrã de computador. O display poderá ser realizado através da implementação de um servidor web. DAQ Pretende-se que o aparato experimental PC esteja ligado pela rede a um micro- computador que será responsável pelo Monitor display. Dept. Física Micro PC Rede
