abstract = {Synchrotron SOLEIL is preparing a machine upgrade with a reduction by more than a factor 10 the horizontal electron beam emittance (< 100 pm.rad)., the future multibend achromat lattice will be composed of a large number of magnet elements. Quadrupole and sextupole strengths will impose a drastic reduction of the vacuum chamber dimensions and in particular its diameter that will be reduced to 10 mm. One of the challenges for the beam position monitors will be the mechanical integration of the 4 buttons and feedthroughs on such a small beam pipe. In this context we have realized a first prototype with Component Off The Shelf 3 mm buttons diameter, to validate this mechanical integration and are starting the 3D electromagnetic simulations to study the impedance characteristics, the RF parameters, the heating and thermal issues.},
