Sensoriamento de altas pressões baseado em espectroscopia.

Abstract

In November 2018, the Government of Brazil inaugurated the particle accelerator called Sirius. The new Brazilian synchrotron light source is one of the most advanced molecular research laboratories in the world. Classified as a fourth-generation synchrotron, this laboratory will provide faster experiments than the current accelerator called UVX. This scenario has been demanded an instrumentation able to provide support to this evolution. Thus, inside of experiment scenarios carried out with high pressures under X-ray incidence, a high-pressure spectroscopy-based technique for high pressure sensing is described in this report. From the study and characterization of the ruby luminescence, this report suggests an algorithm implemented in Python for supervisory applications. In addition, the knowledge about the operation of equipment used in synchrotron laboratories to acquire light spectrum of ruby is reported. Finally, through an evaluation of the developed system, a new model for the processing of the ruby luminescence spectrum for pressure identification is proposed.
