Publikováno v: Physik Journal. 54:219-224

Die Elektron-Positron-Annihilation im Energiebereich zwischen 500 und 1000 GeV ist wegen der Synchrotronstrahlung nicht mehr mit Speicherringen, sondern nur noch mit einem Paar gegeneinander gerichteter Linearbeschleuniger, d. h. mit einem Linearcoll

Rolf Wideröe and the Development of Particle Accelerators

Autor: B. H. Wiik

Publikováno v: Acta Oncologica. 37:615-625

The development of particle accelerators is traced from the simple but ingenious table-top devices conceived during the late 1920s to the present day's large, complex machines which extend over tens of kilometers. The emphasis is on Rolf Wideröe and
