Description
Summary:In this paper, we describe the first caesium atomic fountain primary frequency standard NICT-CsF 1 of National Institute of Information Communications Technology (NICT) in Tokyo, Japan. The structure of the NICT-CsF1 system and evaluation procedure of the systematic frequency shifts and their uncertainties are presented. Typically, NICT-CsF 1 has a frequency stability of 4 x 10.../... and a frequency uncertainty of 1.9 x 10... (ProQuest: ... denotes formulae/symbols omitted.)
