L.G. Smith’s Precision RF-Mass-Spectrometer Transferred from Princeton to Delft

  • E. Koets

Abstract

The operating principles and the essential elements of this very high precision mass spectrometer, as well as the modifications made until August 1971 have been described by Smith (1, 2, 3). Details about improved measurement procedures and instrumental modifications (shielding of insulators, clean-up of the RF-signal, beam blanking during sweep fly back, modification of the optics supplies, etc.) introduced by Smith from August 1971 until July 1972, were given in a recent paper by Smith and Wapstra (4). After completion of these modifications Smith measured the masses of 13C, 14C, 14N, 15N and 16O. Reference (4) also reports on these measurements and on some earlier measurements (masses of 1H, 2H, 3H, 3He, 4He and 19F), partly not published before.
