Xq. Wang et al., RESEARCH ON CHANGES OF FOCUSING STRUCTURE PARAMETERS CAUSED BY THE DC-CLEARING ELECTRIC-FIELD OF STORAGE-RING, Gaoneng wuli yu he wuli, 22(8), 1998, pp. 755-762
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.
