Sistema de controle dos parâmetros relevantes de um criostato contendo argônio líquido (LAr)

Abstract

The project aims to develop a controller for a cryostat, in order to control temperature, pressure and argon level and thus create a cryogenic environment suitable for the detection of neutrinos. The control system is a state-space MIMO controller with the help of a Kalman filter to estimate the values of the quantities. The LABVIEW programming language was used to monitor the mentioned quantities. An alarm system was developed to turn the equipment off if necessary. To view the history of the controlled quantities, a web application was developed. This project will be part of the system that will control the appropriate environment for ARAPUCA, which will be used in DUNE, an international research project on neutrinos.
