Data

Introduction

Raw data files produced by the TDAQ system are transferred to CASTOR by the CDR service, usually within half an hour.

Once on CASTOR filesĀ are available for processing; after calibration and reconstruction the reconstructed data is available, both on CASTOR and EOS, for data quality monitoring, first, and for user analyses, later.

NA62 collects data in files following the beam time structure (bursts) provided by the SPS; each bursts is about 4.5 s long, with an effective spill length of about 3 s. NA62 usually receives two spills per super cycle of the SPS, for 3 to 6 moths per year, according to the SPS schedule; the current status is available on the SPS Page1. Data taking for physics is foreseen from 2015 to 2018.

Data is collected in "runs", i. e. an ensamble of bursts sharing the same experimental conditions.
