Abstract：
This paper describes the construction and the commissioning of the new injection bump system of HLS ring. An emphasis of the discussion is put on various errors of the system and the method of evaluation and reduction. After some improvements and fine adjustment, an average injection rate of 2—6mA/s was obtained in the daily operation and a maximum accumulated current of 400mA achieved. The injection system has run for almost two years and played an important role in the operation of the light source.
