This paper describes the improvements in launching stability and launching velocity of the linear accelerator (LAC).<br>The authors have designed and produced a railgun using the LAC for weaving loom shuttles. The LAC is an electromagnetic launcher which enable a projectile to be launched at a speed of more than 50m/s. It basically consists of an uni-pole linear DC motor and operates the same principle as DC rotary motors, the most difficult problem in this system being the stabilization of the current collection on the projectile.<br>Then we have conducted the various launch experiments. As a result, we have achieved that the carbon projectile was launched at a speed of 73m/s using double-stage type LAC.
