An 80 MHz heavy ion RFQ Linac at Tokyo Institute of Technology (TIT) was constructed for researches on inertial fusion and plasma experiments. The first acceleration was accomplished with low intensity He{sup +} ion beam in 1993. This four vane type RFQ accelerates particles with charge to mass ratio (q/A) of 1/16 from 5 keV/amu to 214 keV/amu. Two-dimensional (2D) machining was applied for cutting of the RFQ vane-tips. The vane parameters for the RFQ were optimized considering the effects of multipole components at inter-vane field. In order to increase the acceleration efficiency synchronous phase was gradually raised from {minus}30{degrees} to {minus}20{degrees} at the {open_quotes}accelerator section{close_quotes}. The beam transmission is expected to be 68.4% for the beam current of 10 mA. Details of the RFQ tuning and performance will be reported.
