Title: The EUSO@TurLab Project,
Abstract: The TurLab facility is a laboratory, equipped with a 5 m diameter and 1 m
depth rotating tank, located in the Physics Department of the University of
Turin. The tank has been built mainly to study problems where system rotation
plays a key role in the fluid behaviour such as in atmospheric and oceanic
flows at different scales. The tank can be filled with different fluids of
variable density, which enables studies in layered conditions such as sea
waves. The tank can be also used to simulate the terrestrial surface with the
optical characteristics of different environments such as snow, grass, ocean,
land with soil, stones etc., fogs and clouds. As it is located in an extremely
dark place, the light intensity can be controlled artificially. Such
capabilities of the TurLab facility are applied to perform experiments related
to the observation of Extreme Energy Cosmic Rays (EECRs) from space using the
fluorescence technique, as in the case of the JEM-EUSO mission, where the
diffuse night brightness and artificial light sources can vary significantly in
time and space inside the Field of View (FoV) of the telescope. Here we will
report the currently ongoing activity at the TurLab facility in the framework
of the JEM-EUSO mission (EUSO@TurLab).
