Abstract
Todos ellos, entre otros, son instrumentos que permiten obtener información distinta y complementaria de la radiación emitida por la materia que existe en el universo. La parte de la radiación que se produce a las más altas energías de fotón que se conocen hoy en día genera una cascada de partículas subatómicas al incidir en la atmósfera terrestre. Esta cascada es la que da origen a la luz detectada por los telescopios que se han estudiado en esta tesis: los telescopios de gran tamaño (LST) de los futuros observatorios Cherenkov Telescope Array (CTA).Habrá dos grupos de telescopis CTA, CTA-Norte en La Palma, España, y CTA-Sur en Atacama, Chile. Actualmente solo un telescopio de CTA-Norte está construido, el LST1, el cual está en fase de puesta en marcha.La vida útil estimada de los LST es de 30 años. Tratar de investigar qué podemos hacer para prolongar esta vida útil de los LST en CTA-Norte es el principal objetivo de esta tesis. Al mismo tiempo, se pretende exponer y defender una serie de recomendaciones prácticas, así como proporcionar información relevante, que puedan ayudar a incrementar la disponibilidad de estos telescopios durante su funcionamiento, reduciendo los esfuerzos de mantenimiento y mejorando la fiabilidad de los subsistemas...
All of them, among others, are instruments that allow us to obtain different and complementary information on the radiation emitted by the matter that exists in the universe. The part of the radiation that is produced at the highest photon energies known today generates a cascade of subatomic particles by impacting the Earth's atmosphere. This cascade is what gives rise to the light detected by the telescopes studied in this thesis: the Large Size Telescopes (LST) of the future Cherenkov Telescope Array (CTA) observatory.There will be two CTA observation stations, Northern Array in La Palma, Spain, and CTA-South in Atacama, Chile. Currently only one telescope from CTA-North has been built, the LST1, and it is in commissioning phase.The expected lifespan of LST is 30 years. To try to investigate what can be done to enlarge this lifespan in CTA-North is the main objective of this thesis. At the same time, it is intended to present and defend a series of practical recommendations, as well as to provide relevant information, that can help to increase the availability of these telescopes during their operation, reducing maintenance efforts and improving the reliability of the subsystems...
