Figure 1
Fill patterns of the ESRF storage ring. There are 992 `buckets', which are spaced by 2.84 ns. In the uniform fill (a), all the buckets are filled by electrons; in the 1/3 fill (b), 2/3 of the buckets are empty; but in the hybrid mode (c), a single bucket in the middle of the empty part is filled. In the 16-bunch mode (d), the bunch interval is 176 ns. |
