Tunka-133: preliminary results from the first year of operation

The new array Tunka-133 started data taking at the end of 2009. The apparatus records the Cherenkov light pulse waveform of extensive air showers (EAS). It consists of 133 optical detectors deployed over an area of about 1 km2. About two million events have been collected during 286 hours of clean moonless nights in winter 2009-2010. Using these data, we present methods of primary cosmic particle parameter reconstruction for EAS with the core both inside and outside the array and give preliminary results.
