The Paul Scherrer Institute (PSI) provides the world$'$s highest intensity muon beam up to $\sim10^{8}\, \mu^{+}/\rm{s}$ at $28\, \rm{MeV/c}$ momentum. The HiMB project aims to improve this rate by two orders of magnitude. Meanwhile, the muCool collaboration is developing a device which converts a standard surface $\mu^{+}$ beam of cm-size and MeV-energy into a beam of 1$\,$mm-size and 1$\,$eV-energy by achieving a compression of 6-dimensional phase space by 10 orders of magnitude with an efficiency of $10^{-3}$.

This talk will focus on the working principle of the muCool project, the various results obtained so far and the aims of the 2019 test beam. Some information about the HiMB project will be also presented. These works are supported by the SNF projects: 200020$\_$172639 and 20021$ \_$137738.
