An RFQ LINAC 'LITL' (Lithium Ion Test Linac) was constructed and accelerated ion beams of H/sup +/, H/sub 2//sup +/, H/sub 3/ +, /sup 3/He +, /sup 6/Li + and /sup 7/Li +. The machine was designed to accelerate particles with charge to mass ratio (q/A) of 1 about 1/7 injected at 5 keV/u up to 138 keV/u. The acceleration cavity of four vane structure is 56 cm in diameter and 138 cm in length. Transmission exceeding 90% has been obtained for proton beam of 80 ..mu..A. The acceleration characteristics agree well with the computer simulation with PARMTEQ. For the acceleration of /sup 7/Li +, an rf power of 22 kW is fed with a loop coupler. In cw operation, an electric field of 205 kV/cm has been applied, which is required for /sup 7/Li + acceleration and corresponds to 1.8 times the Kilpatrick's criterion. A maximum field of 2.0 times the criterion has been achieved, in pulse operation, with a duration width of 5 ms and repetition period of 25 ms. Operation of the machine is easy and stable.
