Zusammenfassung:
In this work an electronics proposal for the full measurement chain of the next-generation ground-based gamma-ray observatory SWGO is elaborated. This project will be based on a km2- scale array of roughly 6000 water
Cherenkov detectors each equipped with multiple photomultiplier tubes
(PMTs) as photosensors. SWGO will be built in South America at an altitude
of over 4000m which requires robust electronics and mechanics.
As the main topic of this thesis the development of a remote-controlled
multi-channel HV device is described. The so-called PhantomHV system
generates high voltage required for the operation of PMTs and shapes
their output signal. It has a modular design, making it easy to install and
replace system components, especially in the field. This device is evaluated,
optimised and prepared for industrial production.
Additionally, a concept for refurbishing already available PMTs for operation
in purified water for an engineering array has been developed.
Another major part of this work describes a concept of how to distribute,
operate and maintain the electronics in the detector field. An autonomously
running environmentally controlled outdoor cabinet is proposed that houses
and provides power to the PhantomHV system and readout electronics in
the field. Two prototypes have been built, one as a proof of concept and a
second destined for a candidate detector site at 4500m asl in the Peruvian
Andes.
