The measurement of the ionization produced by particles in a medium presents a great interest in Dark Matter search. The ionization quenching factor is defined as the fraction of energy released by ionization by a recoil in a medium compared with its kinetic energy. We have developed an experimental setup devoted to the measurement of low energy (keV) ionization quenching factor for the MIMAC project. The ionization produced in the gas has been measured with a Micromegas detector filled with different gas mixtures (He, CF4,...). A new compact and portable ion source will be presented.
