The cluster target is one of two operation modes of HIRFL-CSR internal target system. The cluster beam is obtained by cooling a supersonic gas-jet. The cluster target has been finished and installed to the due position. Several test experiments such as the test of vacuum system, the calibration of the flux and the stability of system have been done after the installation and collimation of cluster internal target.
