Abstract :
In this paper we propose separate measurements of the temperature coefficients of the Cs clock frequency shift caused by Cs-buffer gas (Ar, Ne, N2) collisions, using the CPT interaction. The method of measurement of the temperature coefficients is described and the preliminary results for a Cs vapour cell containing 30 Torr of Ar are shown.
