Super bunches in the hybrid fill pattern of the BSRF, where a camshaft bunch is placed in the middle of a large gap between bunch trains. The beam current of super bunch and small bunches within bunch trains is 9 mA and 2.5 mA, respectively. The total beam current is 250 mA. The data are acquired by a 4 GHz oscilloscope using a fast-response photodiode. |
