Welcome to the CERN Tape Archive!

CERN Tape Archive

The CERN Tape Archive (CTA) is the archival storage system for the custodial copy of all physics data at CERN. CTA is implemented as the tape back-end to EOS. EOS+CTA is the CERN archival solution for LHC Run–3 and beyond.

For a general overview of CTA, see our Publications and Presentations. There is also some general Development and Systems Integration Documentation which complements what is on this site.
