First Edition
Pamphlet. Condition: Near Fine. First Separate Edition. First Separate Edition. 601-604 pages. 7 3/4 x 10 1/4 inches. The four page offprint of this work, reprinted from the Review of Scientific Instruments, Vol. 22, No 8. August 1951. Bright and clean, with some minor creasing. Pamphlet. "The Nobel Prize in Physics 1989 was divided, one half awarded to Norman F. Ramsey [ one author of this paper ] "for the invention of the separated oscillatory fields method and its use in the hydrogen maser and other atomic clocks", the other half jointly to Hans G. Dehmelt and Wolfgang Paul "for the development of the ion trap technique"." (nobel prize site) A cyclotron is a particle accelerator invented in 1934 by Ernest O. Lawrence [ for which he won the Nobel Prize for Physics in 1939 ] in which charged particles accelerate outwards from the centre along a spiral path. (wiki) "The requirements that must be met by a satisfactory dee biasing system are outlined. A successful and simple means of meeting those requirements is described." (abstract) "Because of the large magnitude of the radiofrequency currents and electrical fields inside the cyclotron tank, there are considerable difficulties associated with obtaining a satisfactory system based either on the use of the dee biasing or on the use of grid wires. In the present paper the chief problems which arise in connection with a dee biasing system are discussed." (introduction) Provenance: Davenport estate.
