Laser cooled ions in RF traps have proven useful in a myriad of different domains : quantum computing, metrology, cold chemistry, phase transition studies. In particular, the topological phase transition between 1D and 2D (the chain to zig-zag transition) have been used to study nano-friction and the Inhomogenous Kibble-Zurek mechanism as well as being the main topology used in quantum computing.

In this talk, a method will presented to generate uniformly spaced ion chains as opposite to the standard ion chain, who has a non-uniform density. Such Homogeneous Ion Chain will open the door to the study of the Homogeneous Kibble-Zurek and to quantum gates protocols based on radial modes, to cite some examples.

A new surface RF trap design will be also presented in which the Homogeneous Ion Chain is expected to be realised in the near future.
