Computing ATOMIC NUCLEI
UNIVERSAL NUCLEAR ENERGY DENSITY FUNCTIONAL Computing ATOMIC NUCLEI Petascale computing helps disentangle the nuclear puzzle. The goal of the Universal Nuclear Energy Density Functional (UNEDF) collaboration is to provide a comprehensive description of all nuclei and their reactions based on the most accurate knowledge of the nuclear interaction, the most reliable theoretical approaches, and the massive use of computer power.

Early Synchrotrons in Britain, and Early Work for Cern
EARLY SYNCHROTRONS IN BRITAIN, AND EARLY WORK FOR CERN J. D. Lawson Formerly Rutherford Appleton Laboratory, Chilton, Oxon, UK Abstract Early work on electron synchrotrons in the UK, including an account of the conversion of a small betatron in 1946 to become the world’s first synchrotron, is described first. This is followed by a description of the design and construction of the 1 GeV synchrotron at the University of Birmingham which was started in the same year. Finally an account is given of the work of the international team during 1952–3, which formed the basis for the design of the CERN PS before the move to Geneva. It was during this year that John Adams showed the outstanding ability that later brought the project to such a successful conclusion. 1 EARLY PLANS IN BRITAIN: THE WORLD’S FIRST SYNCHROTRON During the second world war Britain’s nuclear physicists were deployed in research directed towards winning the war. Many were engaged in developments associated with radar, (or ‘radiolocation’ as it was then called), both at universities and at government laboratories, such as the radar establishments TRE and ADRDE at Malvern. Others contributed to the atomic bomb programme, both in the UK, and in the USA. Towards the end of the war, when victory seemed assured, the nuclear physicists began looking towards the peacetime future. The construction of new particle accelerators to achieve ever higher energies was seen as one of the more important possibilities. Those working at Berkeley on the electromagnetic separator were familiar with the accelerators there, and following the independent invention (or discovery?) there of the principle of phase stability by Edwin McMillan in 1945, exciting possibilities were immediately apparent [4]. -

(Signature) ……………………………………………………………………………… 1 Abstract There was no special governmental partnership between Britain and America during the Second World War in atomic affairs. A recalibration is required that updates and amends the existing historiography in this respect. The wartime atomic relations of those countries were cooperative at the level of science and resources, but rarely that of the state. As soon as it became apparent that fission weaponry would be the main basis of future military power, America decided to gain exclusive control over the weapon. Britain could not replicate American resources and no assistance was offered to it by its conventional ally. America then created its own, closed, nuclear system and well before the 1946 Atomic Energy Act, the event which is typically seen by historians as the explanation of the fracturing of wartime atomic relations. Immediately after 1945 there was insufficient systemic force to create change in the consistent American policy of atomic monopoly. As fusion bombs introduced a new magnitude of risk, and as the nuclear world expanded and deepened, the systemic pressures grew. -

It would be impossible to overstate how essential his insight and mentoring have been to this dissertation and my career in general. Just as important has been his camaraderie, which made the researching and writing of this dissertation infinitely more rewarding. Thanks as well to Bruce Hunt for his support. Especially helpful was his incisive feedback, which both encouraged me to think through my ideas more thoroughly, and reined me in when my writing overshot my argument. I offer my sincerest gratitude to the Smith Richardson Foundation and Yale University International Security Studies for the Predoctoral Fellowship that allowed me to do the bulk of the writing of this dissertation.

Introduction When I was approached by the editors of Physics in Perspecti6e to prepare an article on New York City for The Physical Tourist section, I was happy to do so. I have been a New Yorker all my life, except for short-term stays elsewhere on sabbatical leaves and other visits. My professional life developed in New York, and I married and raised my family in New York and its environs. Accordingly, writing such an article seemed a natural thing to do. About halfway through its preparation, however, the attack on the World Trade Center took place. -
Ble Kampen Om Atombomben Avgjort I Telemark? Av Roar Løken
Ble kampen om atombomben avgjort i Telemark? av Roar Løken I tiden som er gått etter 2. verdenskrig, har det vært flere, kanskje særlig krigsbokforfattere og filmfolk, som har gitt uttrykk for de samme tankene: aksjonene i Telemark avgjorde «kappløpet om atombomben». Dersom det er riktig, må det som skjedde her i så fall ha vært blant de viktigste tyske nederlagene under krigen. Dersom tyskerne hadde kunnet skaffe seg atombomber før de allierte, ville utfallet av 2.verdenskrig sannsynligvis ha blitt et annet – et utfall verden heldigvis ble skånet for. Tysk atomforskning Tyskernes interesse for tungt vann (D20)(se s.20!) i tiden rett før og etter krigsutbruddet er åpenbar. Kravene om sterk produksjonsøkning bekrefter inntrykket.1) Men hvor viktig var det – og dermed, hva skulle det brukes til? Aage Bohr, sønn av den danske kjernefysikeren Niels Bohr, kan fortelle at faren høsten 1941 fikk besøk av to tyske kolleger, professorene Werner Heisenberg og C.F. von Weizsäcker. Disse gav uttrykk for at tyske myndigheter tilla atomenergien stor militær betydning. Heisenberg mente at «de nye muligheder kunne komme til at afgøre krigen, hvis denne trak ud».2) Werner Heisenberg, som var en av lederne for den kjernefysiske forskningen i Tyskland, forteller selv i en artikkel i tidsskriftet «Bulletin of the Atomic Scientist»3) at tyske fysikere sommeren 1942 i prinsippet kjente til hvordan en atombombe kunne konstrueres. Det eksplosive stoffet plutonium kunne produseres i reaktorer med tungt vann som moderator. – I praksis var det imidlertid en helt annen sak. Det kunne nok gjøres, men det ville ta lang tid. Frykt blant de allierte De meldingene som kom til London via den britiske etterretningstjenesten de første krigsårene, virket skremmende. -
