Abstract
The changes of focusing structure parameters caused by the DC-clearing electric field of storage ring were researched. The conclusion is mad e that tune shift caused by the DC-clearing electric field is related to the real-time close orbit of stored beam. The clearing electric fie ld asymmetrically distributed along the ring destroys the symmetry of the focusing structure and decreases the acceptance of storage ring. I t has negative effect to the injection and accumulation process in cer tain condition.
