The ATLAS experiment at the Large Hadron Collider is one of the machine's two big all-purpose detectors.
Israel became the 21st member state of CERN, the Geneva, Switzerland-based collaboration that runs underground particle accelerators such as the Large Hadron Collider.
The Israeli flag joined those from 20 other nations in a ceremony today (Jan. 15), after UNESCO officially recognized the new country as a member of CERN, or the European Organization for Nuclear Research. Israel is the first new member of the organization since 1999.
"The Israeli scientific community has brought a great deal to CERN over the years," said CERN Director General Rolf Heuer. "I am looking forward to welcoming Israel as our 21st Member State and to intensifying our collaboration."
The new state's induction comes after a 2010 decision to increase the number of member states at CERN. Before becoming a full member of CERN, Israel had to become an associate member, a status that lacks the full range of rights and responsibilities of full member states. The full member states bear more of the costs of operating and building CERN's big projects, and they also can weigh in on important decisions about future priorities.
Currently, Serbia is also an associate member, and Cyprus and Ukraine should become associate members once their parliaments sign on. Several other countries, including Pakistan and Turkey, have also applied for associate membership.
All of the other member states are in Europe, though the United States and other non-European countries have observer status, meaning they can go to the meetings, but don't get to weigh in on final decisions.
