Part B (10 points)You are going to read a text about the topic of nuclear fusion, followed by a list of explanations(or examples). Choose the best explanation/example from the list for each numbered subheading/generalization. There is one extra explanation/example which you do not need to use.Scientists say they have achieved small-scale nuclear fusion in a tabletop experiment, using tried and true techniques that are expected to generate far less controversy than past such claims.This latest experiment relied on a tiny crystal to generate a strong electric field. While the energy created was too small to harness cheap fusion power, the technique could have potential uses in medicine, spacecraft propulsion, the oil drilling industry and homeland security, said Seth Putterman, a physicist at the University of California at Los Angeles.Putterman and his colleagues at UCLA, Brian Naranjo and Jim Gimzewski, report their results in Thursday's issue of the journal Nature.(41) Held up to ridiculePrevious claims of tabletop fusion have been met with skepticism and even derision by physicists.(42) Sound theoretical basisFusion experts said the UCLA experiment will face far less skepticism because it conforms to well-known principles of physics.(43) Energy in waitingFusion power has been touted as the ultimate energy source and a cleaner alternative to fossil fuels like coal and oil. Fossil fuels are expected to run short in about 50 years.(44) Process of fusionIn the UCL'A experiment, scientists placed a tiny crystal that can generate a strong electric field into a vacuum chamber filled with deuterium gas, a form. of hydrogen capable of fusion. Then the researchers activated the crystal by heating it.(45) Commercial usesUCLA's Putterman said future experiments will focus on refining the technique for potential commercial uses, including designing portable neutron generators that could be used for oil well drilling or scanning luggage and cargo at airports.In the Nature report, Putterman and his colleagues said the crystal-based method could be used in 'microthrusters for miniature spacecraft'. In such an application, the method would not rely on nuclear fusion for power generation, But rather on ion propulsion, Putterman said.'As wild as it is, that's a conservative application', he said.
