The MAGIC Telescope

Abstract

The MAGIC Telescope is an Imaging Air Cherenkov Telescope (IACT) located on the Canary island of La Palma (28.80 N, 17.90 W), at the Roque de los Muchachos Observatory (2200 m above see level). The main goal of the experiment is to cover with high sensitivity the energy region between 10 GeV and 300 GeV in gamma-ray astronomy, which is inaccessible up to now, by lowering the threshold energy Eth as compared to the previous generation of IACTs. Observations in this new window of the electromagnetic spectrum are expected to provide key data for the understanding of a wide variety of astrophysical phenomena belonging to the so-called “non-thermal Universe”, like the acceleration processes in Active Galactic Nuclei, the radiation mechanisms of pulsars and Supernova Remnants, and the enigmatic Gamma Ray Bursts. In addition, MAGIC may also contribute to the understanding of some open questions in fundamental physics, like the Lorentz Invariance, or the Dark Matter in the Universe. This thesis contains detailed studies about the development of new technologies which improved the sensitivity and the performance of the telescope camera. The thesis also reports about the extraction of the first significant gamma-signals from the first observations performed with the MAGIC telescope during the night of 14th-15th February 2004. The sources observed were the Crab nebula, which is a Supernova Remnant located at 2 kpc away from the solar system; and Markarian 421, which is an Active Galactic Nuclei located at a red shift z = 0.031. Das MAGIC-Teleskop ist ein abbildendes Luftschauer-Cherenkov-Teleskop welches auf der Kanarischen Insel La Palma (28,8° N, 17.9° W), auf dem Gelände des Observatorio del Roque de los Muchachos, in 2200 m Höhe installiert ist. Das Ziel des Experimentes besteht darin, mit hoher Sensitivität Gamma-Astronomie im bisher nicht beobachtbaren Bereich von 10 GeV bis 300 GeV zu betreiben. Das Experiment erreicht dies durch die Senkung der Energieschwelle im Vergleich zu bisherigen abbildenden Cherenkov-Teleskopen. In diesen neuen Fenster im elektromagnetischen Spektrum werden Schlüsseldaten für das Verständnis einer Vielzahl astrophysikalischer Phänomene des nichtthermischen Universums erwartet, wie die Beschleuningsprozesse in Aktiven Galaktischen Kernen, die Strahlungsmechanismen von Pulsaren, von Supernova-Überresten und den noch immer rätselhaften Gammy Ray Bursts. Darüberhinaus könnte MAGIC auch zur Beantwortung offener grundlegender Fragen der Physik beitragen, wie sie sich beispielsweise im Zusammenhang mit Dunkler Materie im Universum oder im Bezug auf eine eventuelle Verletzung der Lorentz-Invarianz stellen. In der vorliegenden Arbeit werden detaillierte Studien zur Entwicklung neuer Technologien vorgestellt, welche die Sensitivität und Leistungsfähigkeit der Photomultiplier-Kamera des MAGIC-Teleskops verbessern konnten. Darüberhinaus wird über die Gewinnung erster signifikanter Signale aus Beobachtungen, die mit MAGIC in der Nacht vom 14. zum 15. Februar 2004 durchgeführt wurden, berichtet. Die beobachteten Quellen waren der 2 kpc entfernte Krebsnebel (ein Supernova-Überrest) sowie Markarian 421, ein Aktiver Galaktischer Kern mit einer Rotverschiebung von 0.031.
