BaikalGVD: The next-generation neutrino telescope at the lake Baikal

Abstract: The neutrino telescopes located in the lake Baikal have been one of the key players in the field of neutrino astronomy for many decades. In April 2015, the first part (cluster) of the newly constructed next-generation neutrino telescope, Gigatone Volume Detector (GVD), was put into operation in the lake Baikal and started to take data. In the beginning of 2017 the second cluster was installed which doubles the number of Optical Modules (OMs) as well as the effective volume. Moreover, the substantial extension of this detector is planned in the next few years, since another two clusters are going to be installed every consecutive year. In total 8 clusters of 2304 OMs with overall effective volume ~ 0.4 km3 will be deployed by 2020.

In this talk, the description of the detector itself and of the detection mechanism are going to be given. The installation procedure of the detector as well as the time calibration used at GVD are going to be described. Moreover, the measurements of the Time Walk Effect (TWE), which influence the precision of time measurements, in situ are going to be introduced. Also the simulations and the first preliminary tests of the possible future GVD extension (“BaikalTop”) is going to be presented.

Seminar takes place on Tuesday, October 3rd 2017 at 2:00 PM
in the IEAP meeting room, Praha 2 ‐ Albertov, Horská 3a/22.
