All the links in the LHC’s cryogenic chain are being examined with a fine-tooth comb in order to detect and correct any issues

The re-filling of the arcs with liquid helium started last week, and the LHC is gradually being prepared for electrical tests at the end of the month

Some 120 experts in cryogenic safety met at CERN for the first Cryogenic Safety Seminar. Their discussions included Kryolize, a new CERN technology

In this week's Bulletin find out how a new LHCb programme is delving uncharted waters for the LHC: exploring how protons interact with noble gases

The CERN cryogenics team are filling the LHC with liquid helium, cooling entire sections to below 4K

The cryogenic system that cools the LHC's superconducting magnets is the largest and most advanced of its kind
