Title: Very Forward Calorimetry at the LHC--Recent results from ATLAS

Abstract

We present first results from the ATLAS Zero Degree Calorimeters (ZDC) based on 7 TeV pp collision data recorded in 2010. The ZDC coverage of {+-}{approx}350 {mu}rad about the forward direction makes possible the measurement of neutral particles (primarily {pi}{sup 0}'s and neutrons) over the kinematic region x{sub F} > or approx. 0.1 and out to p{sub T} < or approx. 1.2 GeV/c at large x{sub F}. The ATLAS ZDC is unique in that it provides a complete image of both electromagnetic and hadronic showers. This is illustrated with the reconstruction of {pi}{sup 0}'s with energies of 0.7-3.5 TeV. We also discuss the waveform reconstruction algorithm which has allowed good time-of-flight resolution on leading neutrons emerging from the collisions despite the sparse (40 MHz) sampling of the calorimeter signals used.
