Measurement Techniques Aims and scope

An overview of the research results obtained at the All-Russia Research Institute of Physicotechnical and Radio Measurements when creating a fountain type clock is presented. The possibility of using the results obtained for the development of a sensitive atomic interferometer (gravimeter) based on cold rubidium atoms is analyzed. The relevance of the study lies in assessing the prospects for creating an interferometer (gravimeter) based on cold rubidium atoms for absolute measurements of the local value of the gravitational acceleration. The physical principles of operation of an atomic gravimeter are described. A comparison is made between an atomic gravimeter and a fountain-type frequency standard based on cold atoms. The technical solutions required for the creation of an atomic gravimeter with given values of the sensitivity for measuring the acceleration of gravity are proposed. To achieve a gravimeter sensitivity of the order of 1 μGal/Hz1/2, the phase noise of laser radiation, the pressure of residual gases in the vacuum system, and the parameters of the magnetic shield system are estimated.
