Accelerator & CDF performance Tevatron is the world highest energy accelerator at S=1.96 TeV. CDF will be able to take data until to 2010. Data processing and analysis will be done five more years after that. Data taken 4.1 fb-1 (Nov. 2008) 5~6 fb-1 till by 2009

Network between Korea-Fermilab GLORIAD ESNet Mathis Equation BW: Upper bound of TCP throughput MSS: Max Segment Size RTT: Round Trip Time P: Packet Loss Nov. 2005 vs. Jan. 2009

CHEP(Korea) – Fermilab Nov. 10~24, 2005 (2 weeks) Packet loss is low. RTT is unstable. 2019년 4월 25일
