Description
IceCube is a cubic kilometer scale neutrino telescope at the South Pole, Antarctica.
It consists 5160 light sensors deployed in 86 holes between 1450 meters and 2450
meters depth in the transparent ice. The holes have been drilled with a hot water
technique, creating water filled holes with a diameter of 60 cm in which the light
sensors were deployed before the water froze again. In order to investigate the
optical properties of the newly frozen ice in the holes, an optical recording system
consisting of two movable video cameras instrumented with lasers and lamps was
deployed in the final IceCube hole on the 18th of December 2010 at a depth of 2455
meters. Video was recorded as the system descended during deployment and during the
freezing of the hole. We will present the observations made by the camera system and
discuss what has been learned for future drilling.
