'Dragon-I' is a high current pulse electron linear induction accelerator designed and constructed in IFP/CAEP. It generates a 20MeV, 2.5kA, 60ns pulse electron beam. The whole facility has three parts: injector; accelerator and beam focus system. The accelerator consists of 72 induction cells and 18 connection cells. A solenoid was installed inside each cell forming beam transport sysem. During the initial beam test both high frequency and low frequency oscillation were found. A lot of simulation and experiment investigations were done to get the transverse impedance of the cells and the corkscrew motion of the electron beam. Details of both the simulation and the experimental methods to correct the instability are presented.
