Microgravity at "home"!

Our ZERO-G simulator allows us to launch our 200 kg Cold atom sensor in our lab and gives us access to 500 ms of microgravity every 12 s, in a highly repeatable way. It consists in reproducing a perfect parabola trajectory by controlling and servo locking the position of the experiment thanks to laser rulers and vibrations-free displacement systems. We expect to increase the interrogation time and the sensitivity of our instrument and consequently reach a level of 10-11 for the test of the Weak Equivalence Principle.
