The unit of energy used in particle physics is the electronvolt (eV) which is the amount of energy picked up by an electron passing between the poles of a one-volt battery. Energies of a few eV are sufficient to pull electrons from atoms. Energies a million times higher (MeV,) are involved when dealing with nuclear phenomena such as fission in reactors. To study the constituent particles of the nucleus, energies at least a thousand times higher still (GeV), are needed. The CERN antiproton project described here makes possible the highest collision energies ever achieved, but the total energy in the proton and anti-proton beams is still very small. What is important is that this energy is concentrated in a tiny amount of matter in the particle beam. 相似文献

<正>Soft Landing on the Far Side of the Moon On January 3, 2019, the Chang’e 4 probe sent back photos of the Von Karman crater in the South Pole-Aitken basin, after its successful soft landing, the first ever by a man-made vehicle, on the surface of the far side of the moon. This feat was hailed as opening a new chapter in mankind’s lunar exploration. CAS researchers made significant contributions to the mission. 相似文献

CAS is the highest academicorgan in natural sciencesand a national multi-disci-plinary center for science and high-tech development in China. It is notonly a key component in the nationalsystem of S&T research anddevelopment, but also a vehicle forthe popularization of S&Tknowledge. Acting as a think tankand database, it is endowed with keyduties in spreading scientificknowledge, encouraging scientificspirit, and giving publicity to scien-tific ideas and related methodology.Over the past 50… 相似文献

CAS launched a plan to develop key laboratories in 1984. By now, it is home to one State laboratory, 55 State key laboratories (including laboratories under the joint sponsorship of CAS and Ministry of Education) and CAS key laboratories. Besides, the preparatory work for establishing three new State laboratories is under way. 相似文献
