Resumo


Resumo: O experimento LHCb será submetido a um upgrade para se adequar aos novos regimes de luminosi-dade que o LHC oferecerá. As estações de traço atuais não são adequadas para funcionar sob os níveis de ocupação esperado, e por isto o upgrade também compreenderá troca dos atuais detectores das estações T1, T2 e T3. O novo detector será composto por fibras cintilantes, enquanto o antigo compreendia tubos de Straw e tiras de silício. A atualização requer não somente o desenvolvimento do novo detector em si como também o desenvolvimento de nova eletrônica de front-end. Neste contexto, o CBPF se insere como responsável por de-senvolver um sistema de teste para validação dos módulos eletrônicos durante a etapa de produção da eletônica e validação do detector durante a etapa de montagem. O presente trabalho consiste no desenvolvimento de um sistema de controle para os testes mencionados, que compreendem a validação de toda a eletrônica de aquisição, a configuração da mesma para funcionar juntamente com o sistema supervisório (SCADA) do projeto e o de-senvolvimento de painéis para controle e monitoramento de registradores internos à front-end.

Abstract: The LHCb experiment The LHCb experiment will undergo an upgrade to suit the new levels of luminosity that the LHC will offer. The current tracking stations are not suitable to work under the occupancy levels expected, and this upgrade will include the exchange of current detectors of stations T1, T2 and T3. The new detector will consist of scintillating fibers while the former comprised of Straw Tubes and silicon strips. The update requires not only the development of the new detector itself as well as the development of the front-end electronics. In this context, CBPF is inserted the responsible for developing a test system to validate the electronic modules during the production step of the electronics and validation of the detector during the assembly step. This work consists in the development of a control system for the mentioned tests, that includes validation of all acquisition electronics, its configuration to work with the supervisory system (SCADA) used in the design and development of panels for control and monitoring of internal registers in the front end.

Keywords: LHCb; LHC; Upgrade; Scintilating Fibers Detector; SCADA; Control system.
