Abstract：
The improved design of the higher order modes(HOMs) couplers with TESLA style has been discussed, and the experiment study on the improved coupler has been done. Comparison of the experimental result with the simulation result shows that the improvement of the HOMs Coupler is successful in HOMs damping.
