Advanced Double Pulse Detection Techniques in the Baikal-GVD Neutrino Telescope

AbstraktAbstract

The aim of the Master thesis is the Baikal-GVD (Gigaton Volume Detector) neutrino telescope which is located in the biggest freshwater lake in the world – Lake Baikal. The goal is to detect almost undetectable neutrinos having their origin in the Universe. The Baikal-GVD detector is a three-dimensional array of light sensitive sensors – photomultipliers that register light from secondary charged particles at the bottom of the lake. High energy tau neutrino identification is a direct proof of the astrophysical neutrinos detection. The high energy tau neutrinos cannot be created in the collisions of charged cosmic particles in our atmosphere. A large amount of double pulses created in the detector is a typical signature of the tau neutrino registration. Their possible identification is therefore determined by a development of a precise method which can identify double pulses reliably.
