Comparison of brilliances for SPring-8 (black dashed curves) and SPring-8 II (red solid curves). Undulator parameters for SPring-8: period λu = 32 mm, number of periods N = 141 and total length Lu = 4.5 m. Undulator parameters for SPring-8 II: λu = 23 mm, N = 156 and Lu = 3.6 m. Maximum K value is 2.3. |
