The linac of Shanghai Synchrotron Radiation Facility(SSRF) includes an electron gun
a sub-harmonic cavity
a fundamental buncher and four accelerators.It provides 150 MeV electron beams to the booster through the low energy transport line.Installation of the linac started in December 2006
the first beam was obtained in May 2007
and it achieved the designed specification in October 2007.In this paper
we present the installation of waveguide for the linac
the measurement and adjustment of waveguide phase length
