The magnet design of the MAX IV 3 GeV storage ring replaces the conventional support girder + discrete magnets scheme of previous third-generation light sources with a compact integrated design having several consecutive magnet elements precision-machined out of a common solid iron block.
Multilateral arms regulations may restrict or prohibit the production and possession of specific weapons (the disarmament approach) or the use of specific weapons considered excessively inhumane or indiscriminate in their effects (the humanitarian law approach). This article focuses on the second approach, seen against the background of the St Petersburg Declaration of 1868, which states that whenever scientific developments lead towards improvement in armaments, the Contracting Parties will `come to an understanding' in order to `conciliate the necessities of war with the laws of humanity'. The article discusses the prospects for and the legal arguments against battlefield laser weapons which can cause permanent blindness on human beings. Since aggressive use of force is forbidden under the UN Charter, it follows that any use of any weapon is prohibited within the context of aggression. But where international law does not prohibit the use of armed force — as in the case of self-defence or Security Council mandated actions — the right of parties to the conflict to choose methods and means of warfare is not unlimited. The argument is made that systematic use of laser-beams against the eyesight of individuals is prohibited under the existing law of warfare. It is also argued that the use of anti-eye laser weapons is prohibited under existing law, although this conclusion will need to be confirmed in a multilateral document.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
