  Mul­ti­pactor (MP) is an un­de­sired phe­nom­e­non of res­o­nant elec­tron build up en­coun­tered on par­ti­cle ac­cel­er­a­tors. It can in­duce anom­alous ther­mal losses, higher than the Joule losses, in­duc­ing a de­crease of the su­per­con­duct­ing cav­i­ties qual­ity fac­tor, it can even lead to a cav­ity quench. On cou­plers, it can pro­duce ir­re­versible dam­ages or gen­er­ate a break­down of their vac­uum win­dow. Mul­ti­pactor may lead to Elec­tron Cloud build up as well. The ac­cel­er­a­tor group at LPSC has de­vel­oped a test bench ded­i­cated to the mul­ti­pactor stud­ies. This paper pre­sents the ex­per­i­men­tal set-up and its first mea­sure­ments.
