CERN Courier July/August 2014 A PASSION FOR PERFECTION Faces & Places C OLLABORATION Turkey to become associate member state of CERN On 12 May, CERN and Turkey signed an agreement admitting Turkey to CERN associate membership, subject to ratifi cation by the Grand National Assembly of Turkey – the Meclis. Turkey was granted observer status at CERN in 1961, and Turkish physicists are today active in the ALICE, ATLAS, CMS and LHCb experiments at the LHC. They are also involved with CAST, NA63 and OPERA, as well as with experiments at the ISOLDE facility. Turkey operates a Tier-2 centre of the Worldwide LHC Computing Grid, and 110 Turkish scientists are registered users of CERN’s facilities. Turkey’s associate membership will allow it to attend CERN Council meetings and open up industrial collaborations. Turkish scientists can also become CERN staff Taner Yildiz, Turkish minister for energy and natural resources, left, and CERN’s members and participate in CERN’s training director-general, Rolf Heuer, together with the signed agreement.
