n_TOF

• #143 nTOF tests on EOSCTAPUBLIC PPS , #161 Spinners space on EOSCTA PPS
• EOS fix to archive through spinner space deployed on PPS
• n_TOF have done a successful functional test
• Any other blockers or can we schedule the migration?

CLIC/ILC

• Migration 1st week in June (provisional). Review w/c 10 May.

COMPASS

• #69 COMPASS tests on EOSCTAPUBLIC PPS
• COMPASS snaphot imported to eosctapps. Some tapes disabled as not available due to repack and/or drive type not available.

Other Use Cases

• LEP tapepools: postponed until more files have been repacked.

14:20 → 14:30 CTA PUBLIC New Use Cases

• #271 Spacal.
• #274 FASER experiment on CTA

• AWAKE RQF1735636 - Archive 13 TB of AWAKE Run-1 data in /eos/experiment/awake Script to make FTS .json file.

• RQF1747988 CERN Digital Memory, #267

• RQF1790785 TOTEM files to copy from EOS. Everything ready from our side. We could help them by giving them the script to make the .json file.
