Beyond 'big Bang'

摘要

While tunnellers note their major recent contribution to CERN's Large Hadron Collider (LHC) project that went live this month,the hunt for 'Big Bang' knowledge already has another,bigger excavation project in the pipeline-the International Linear Collider (ILC). Last year,plans announced for ILC called for approximately 72km of new tunnels,including: twin 31km long,4.5m diameter parallel tubes;a 7km long circular bore,5m in diameter,between the main tubes;and,13 access major shafts.
