A new method for lengthening SR pulses periodicity in HLS

A new method for lengthening SR pulses periodicity in HLS 1 first-author 1 1 1 National Synchrotron Radiation Laboratory (NSRL), University of Science and Technology of China (USTC), Hefei 230029 National Synchrotron Radiation Laboratory (NSRL), University of Science and Technology of China (USTC), Hefei 230029 Hefei synchrotron radiation Light Source (HLS) is a low energy Synchrotron Radiation (SR) facility. The SR produced from the HLS is in a series of pulses with a strict time structure. To meet some experiments which need long interval SR pulses, a new method, local vertical bump, was proposed. Physical calculations and numerical simulations have been done to demonstrate its feasibility. Time structure Bump orbit Trim coil Kicker References Mattison T et al .
