Gangneung-Wonju National University (GWNU)
*also CERN-SFT (GEANT-V Team)
Collaborators :
IPN-Lyon (Imad Laktineh)

2. CALICE-KNU with Si-W ECAL, 2004 (LAL & LLR)
D.O. Electronics(PCB), Korea

3. ALICE-TOF production, and maintenance (INFN-Bologna, Salerno, ITEP)
R&D of MRPC
ALICE-TOF production, and maintenance
(INFN-Bologna, Salerno, ITEP)

4. Development of High Performance Resistive Plate Chambers
Semi-Digital Hadronic Calorimeter (SDHCAL) for future leptonic colliders proposed by Professor Imad Laktineh in 2006 : Use Glass RPCs and Semi-digital (2-bit) readout, i.e., not expensive & of good performance
IPNL-GWNU Collaboration : SDHCAL module using the Multi-gap Resistive Plate
Chamber
Effective area : 1m x 1m ( 2m x 1m )
signal pad segmentation : 1cm x 1cm
electrodes : 96 x 96 square pads
time resolution : better than 100ps
counting rate : better than 1,000Hz/cm2
Eco-friendly gas instead of freon R-134a (Tetrafluorethane, C2H2F4) to run RPCs
HFE-1234ze (Tetrafluoroprofene, C3H2F4)

5. SDHCAL vs ALICE-TOF
1ns
50ps
96x96
2x48

6. AIDA-2020 since May 2015, funded by Korea/NRF and FKPPL
Thank you for welcoming GWNU(KNU) back to CALICE
