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). [...]

A Disk-based Archival Storage System Using the EOS Erasure Coding Implementation for the ALICE Experiment at the CERN LHC
/ Ahn, Sang Un (KISTI, Daejeon) ; Betev, Latchezar (CERN) ; Bonfillou, Eric (CERN) ; Han, Heejune (KISTI, Daejeon) ; Kim, Jeongheon (KISTI, Daejeon) ; Lee, Seung Hee ; Panzer-Steindel, Bernd (CERN) ; Peters, Andreas Joachim (CERN) ; Yoon, Heejun (KISTI, Daejeon)
Korea Institute of Science and Technology Information (KISTI) is a Worldwide LHC Computing Grid (WLCG) Tier-1 center mandated to preserve raw data produced from A Large Ion Collider Experiment (ALICE) experiment using the world’s largest particle accelerator, the Large Hadron Collider (LHC) at European Organization for Nuclear Research (CERN). Physical medium used widely for long-term data preservation is tape, thanks to its reliability and least price per capacity compared to other media such as optical disk, hard disk, and solid-state disk.

(Bergen U.) et al.
The first evaluation of an ultra-high granularity digital electromagnetic calorimeter prototype using 1.0-5.8 GeV/c electrons is presented. The $25\times10^6$ pixel detector consists of 24 layers of ALPIDE CMOS MAPS sensors, with a pitch of around 30~$\mu$m, and has a depth of almost 20 radiation lengths of tungsten absorber. [...]

The first disk-based custodial storage for the ALICE experiment
/ Un Ahn, Sang (KISTI, Daejeon) ; Kim, Jeongheon (KISTI, Daejeon) ; Han, Heejune (KISTI, Daejeon) ; Lee, Seung Hee (KISTI, Daejeon) ; Yoon, Heejun (KISTI, Daejeon)
We proposed a disk-based custodial storage as an alternative to tape for the ALICE experiment at CERN to preserve its raw data. The proposed storage system relies on Redundant Array of Independent Nodes (RAIN) layout – the implementation of erasure coding in the EOS storage suite, which is developed by CERN – for data protection and takes full advantage of high-density Just-Bunch-Of-Disks (JBOD) enclosures to maximize storage capacity as well as to achieve cost-effectiveness comparable to tape.

In November 2018, the KISTI Tier-1 centre started a project to design, develop and deploy a disk-based custodial storage with error rate and reliability compatible with a tape-based storage. This project has been conducted in collaboration with KISTI and CERN; especially the initial design was laid out from the intensive discussion with CERN IT and ALICE. [...]
