Аннотация: The MASS (Multi-Aperture Scintillation Sensor) instrument consists of a 14-cm oﬀ-axis reﬂecting telescope and a detector unit which measures the scintillations of single stars in four concentric zones of the telescope pupil using photo-multipliers. Statistical analysis of these signals yields information of the vertical turbulence proﬁle with a resolution of dh/h=0.5. We describe the instrument and present the results of its ﬁrst ﬁeld tests, including comparisons with DIMM seeing monitor and generalized SCIDAR. MASS will be used to obtain the extensive statistics of turbulence proﬁles at potential sites of future giant telescopes, as needed to predict the quality of adaptive seeing compensation.
