CEPC Technical Design Report: Accelerator
/ CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar). [...]

Model Independent Approach of the JUNO $^8$B Solar Neutrino Program
/ JUNO Collaboration
The physics potential of detecting $^8$B solar neutrinos is exploited at the Jiangmen Underground Neutrino Observatory (JUNO), in a model independent manner by using three distinct channels of the charged-current (CC), neutral-current (NC) and elastic scattering (ES) interactions. [...]

CERN Tape Archive: production status, migration from CASTOR and new features
/ Cano, Eric (CERN) ; Bahyl, Vladimír (CERN) ; Caffy, Cédric (CERN) ; Cancio, Germán (CERN) ; Davis, Michael (CERN) ; Kotlyar, Viktor (Kurchatov Inst., Moscow) ; Leduc, Julien (CERN) ; Lin, Tao (Beijing, Inst. High Energy Phys.) ; Murray, Steven (CERN)
During 2019 and 2020, the CERN tape archive (CTA) will receive new data from LHC experiments and import existing data from CASTOR, which will be phased out for LHC experiments before Run 3.This contribution will present the statuses of CTA as a service and of its integration with EOS and FTS and the data flow chains of LHC experiments.The latest enhancements and additions to the software as well as the development outlook will be presented. With the development of the repack function, a necessary behind-the-scenes feature, CTA can now take over custodial data and handle media migration, compaction and failures. [...]
