Abstract :
Summary form only given, as follows.We point out key points of a microgravity clock using cold Cs atoms. The main characteristics of the experimental set-up (resonator, optical set-up, ...) are presented. Preliminary tests of a prototype are performed in the reduced gravity of aircraft parabolic flights.
