The China Spallation Neutron Source (CSNS) complex consists of anH$^-$ linear accelerator, a rapid cycling synchrotron acceleratingthe beam to 1.6 GeV, a solid tungsten target station and instrumentsfor spallation neutron applications. The facility operates at a25-Hz repetition rate with an initial design beam power of 120 kWand is upgradeable to 500 kW. The primary challenge is to build arobust and reliable user-friendly facility with upgrade potential ata fraction of the "world standard" cost. Success of the projectrelies on the results of prototyping research {&} development(R{&}D) of key technical systems and components. This paperdiscusses the prototyping experiences of the past two and a halfyears.
