For practically 70 years, CERN, the European particle physics laboratory close to Geneva, has served as a slim however sturdy cultural bridge between East and West. But that hyperlink, which endured the coldest days of the Cold War, is straining beneath the weighty repercussions of Russia’s invasion of Ukraine. Some Ukrainian physicists are calling for Russia to be expelled from the laboratory, web site of three Nobel Prize–successful discoveries and residential to the world’s largest atom smasher, the Large Hadron Collider.
“CERN as a leading scientific laboratory should terminate immediately any cooperation with Russian institutions, because otherwise every crime and every injustice made by their government and their armed forces is seen as legitimate,” says a Ukrainian physicist in Kyiv who works on an experiment at CERN. “We call on democratic society, on scientific society, to stand with us against this tyrant [Russian President Vladimir Putin].”
The CERN Council, which includes representatives from the lab’s 23 member nations, will meet in a particular session on 8 March to determine how to reply to the disaster. Even physicists who extol CERN’s historic position as an engine for peace anticipate the council to sanction Russia in a roundabout way. “There will be a clear sign towards the Russian government,” says Christoph Rembser, a CERN physicist. “I can’t imagine anything else.”
Established in 1954, CERN aimed from its inception to assist promote peace in postwar Europe, says John Ellis, a theoretical physicist from King’s College London who works at CERN and was on the lab’s employees for greater than 40 years. “One of CERN’s mottos is ‘science for peace,’” he says. “And that goes back to the 1950s, when CERN was actually a meeting place for scientists from the Soviet Union and the U.S. and Europe.” Maintaining such ties is vital, particularly in a time of battle, Ellis says, noting that CERN didn’t expel Russian scientists when the Soviet Union invaded Czechoslovakia in 1968 or Afghanistan in 1979. “My personal attitude is that we should really strive to maintain that collaboration, if it’s at all politically possible.”
Rembser, who grew up in what was then West Germany, arrived as a scholar at CERN in 1989, simply after the Chinese authorities massacred protesters in Tiananmen Square. He says that within the aftermath, CERN served as a approach station for Chinese scientists and college students fleeing to the West. The barracks through which Rembser stayed grew so crowded that he needed to take turns sleeping in a mattress. “I was woken up by a guy saying, ‘Now it’s my turn,’ and when I came back, there was another Chinese guy in my bed, too,” he says.
Currently, CERN researchers are striving to assist their 40 or so Ukrainian colleagues. Ellis says he’s attempting to assist a specific Ukrainian colleague and refugee organize a short lived place at CERN, and Rembser is main a committee to assist Ukrainians. CERN personnel have already amassed a lot assist they might rent vehicles to drive the provides to Ukraine’s border with Poland, Rembser says. Emails seen by ScienceInsider counsel CERN administration is working to increase the stays of Ukrainian researchers already on the lab.
The Ukrainian physicist says CERN must also sever ties with Russia. “Keeping these connections, even on the scientific level, will give these gangsters a chance to further manipulate and terrorize our country and the whole of Europe.”
But expelling Russian researchers from CERN could possibly be impractical, Ellis says. More than 1000 Russians work there, he says—roughly 8% of the 12,000 scientists who collaborate at CERN. Their sudden departure would possibly depart the laboratory unable to perform. Complicating the matter, Ukraine is an affiliate member of CERN, which means though it has no seat on the council, it pays dues. Russia is merely an observer nation that pays no dues. But it contributes considerably to particular experiments—very similar to the United States.
Everyone ScienceInsider spoke to acknowledged that the state of affairs has no easy resolution. For instance, the Ukrainian physicist notes that, on a private stage, Russian colleagues at CERN have been form and supportive. Many Russian physicists have spoken out in opposition to the conflict, Rembser notes, which may put them in danger in the event that they return to Russia. So CERN may expertise an inflow of each Ukrainian and Russian physicists in search of refuge, he says.
Whatever the CERN council decides to do subsequent week received’t hinge on the desires of physicists, researchers say. “The scientists sitting around the table may express their opinions,” Ellis says, “but it’s basically going to be a political decision.”
For the second, the Ukrainian physicist in Kyiv is secure. “The last day and night were relatively calm in comparison with the previous one where we suffered from the couple of massive airstrikes.”
