CASTOR very forward calorimeter performance in 2013 data in pPb and pp collisions

CASTOR has taken data since the beginning of LHC operation in 2009. In 2012 the calorimeter has been upgraded with radiation hard PMTs. Improvements in detector mechanical components and services were also important part of the upgrade program. Right after re-installation in CMS the calorimeter successfully took data in 2013 when LHC was colliding first proton and ion beams (pPb) at the center of mass energy of 5.02 TeV per nucleon and then pp beams at the center of mass energy of 2.76 TeV. A set of performance plots, as obtained using reconstructed calorimeter signals in pPb and pp collision events, are presented here. CASTOR response correlation with other CMS sub-detectors (tracker, HF, ZDC) is discussed.
