Felicia was an American ferret briefly used to clean narrow pipes in Fermilab, then known as the National Accelerator Laboratory, during the 1970s.[1][2][3]
Biography
In the 1960s and 1970s, scientists at the National Accelerator Laboratory adjacent to Batavia, Illinois in the United States designed a particle accelerator known as the Main Ring. A large ring of narrow tubing, 4 mi (6.4 km) in circumference, was necessary to its function. However, small pieces of debris littered the narrow tube. Scientists had difficulty finding out how to clean the tubing.[2]
In 1971, Robert Sheldon, a scientist visiting from Britain, suggested that they use a ferret. He knew that poachers sent ferrets into narrow tunnels in Yorkshire to hunt for rabbits.[4] The NAL purchased Felicia from a farm in Gaylord, Minnesota. They chose Felicia for her small size in comparison to other ferrets; she was 15 in (38 cm) long. Scientists trained her to scamper through increasingly long tubes so she could work in the particle accelerator. They placed a diaper and a collar with a long string on her, then had her go through the tube. When she emerged from the other end, they attached a cleaning swab to the string and pulled it through, clearing the tube of debris. Staff incentivized her with raw meat and fish.[5] Walter Pelczarski, the mechanical designer of the lab who was in charge of Felicia, said that ferrets' natural curiosity made Felicia ideal for the job.[2]

Felicia refused to actually enter the Main Ring after her period of training, so she was assigned to shorter, straight lengths of tube in the NAL's Meson Lab.[2] Engineer Hans Kautzky designed a magnet attached to a steel cable to clean the circular Main Ring accelerator, which was dubbed a "magnetic ferret."[4] The Main Ring was officially closed in 1997, making way for Fermilab's Main Injector.[6]
Local media learned about Felicia, and she featured in contemporary news stories and radio shows about the NAL.[5] One writer for the Chicago Sun Times described her as an "atomic age pipe cleaner" in 1971.[7]
Felicia retired after a dozen runs in the Meson Lab. She spent much of her time either at a nearby mink farm or as a pet in the homes of NAL staffers. She died on May 9, 1972, of a ruptured intestinal abscess. Although a local newspaper, The Village Crier, reported plans to taxidermy her body, Felicia's final resting place is not known.[2]
