dc.descriptionIn order to develop new techniques for the knowledge of the universe some experiments in elementary particles and high energy physics are proposed, where progress on detector and data acquisition techniques is fundamental. This project presents some improvements for the LHCb upgrade that will be performed in the period between 2018 and 2019 during the Long Shutdown 2 of the CERN experiments in order to configure, improve and re-structure the data acquisition practices. It will emphasize the Scintillating Fibers detector (SciFi), one of LHCb's future sub-detectors in charge of the trace pattern recognition based on the hits occurred on this sub-detector and the recording of significant events in the data transmission. Due to the proposed changes of the LHCb upgrade, regarding the increase of the luminosity and the collision center-of-mass energy, it is essential to reconsider the digital processes in the data acquisition and their respective processing among the transmission channels, due to the high velocities at which they occur. Therefore, the operation mode configurations in the acquisition digital boards were the aim of this work. And as such, the current condition of the detector and its acquisition techniques and protocols are documented corresponding to their modification. This paper shows a step-by-step presentation of the modifications applied to the codes to move from a Standard Mode to a Wide Bus Mode, increasing the data rate by means of the quantity reduction of the control bits to enlarge the amount of analyzable information among the events. en-US
dc.descriptionLas tarjetas de adquisición se servirán de la actualización del LHCb, que tendrá lugar en el periodo entre 2018 y 2019, durante el Long Shutdown 2 de los experimentos del CERN. Estas mejoras apuntan a la configuración y reestructuración de las técnicas de adquisición de datos, debido al incremento en la luminosidad y correspondientemente con su energía de centro de masa actual. Por lo tanto, se documenta la condición del detector, sus técnicas de adquisición y sus protocolos. Se hará énfasis en las Fibras de Centelleo (SciFi), uno de los futuros subdetectores del LHCb, encargado del reconocimiento de patrones de trazas, basado en los cruces o impactos que ocurren sobre sus fibras, además del registro de eventos significativos en la transmisión de datos. Este artículo presenta paso a paso las modificaciones aplicadas a los códigos para pasar del Modo Estándar al Modo de Bus Ampliado, incrementando la tasa de datos mediante la reducción de bits de control, para acrecentar el número de información analizable sobre los eventos.es-ES
