The Orbit Study on the SRRC 1.3 GeV Booster Synchrotron During Ramping

The closed orbit of electron beam of the SRRC booster synchrotron was measured during ramping from 50 MeV to 1.3 GeV. The beam position monitoring system has been completely modified such that the horizontal and the vertical beam positions can be obtained simultaneously. An HP VXI system combined with some custom made electronic devices was used to acquire and analyze the data. In this study the detailed beam orbits during ramping under specific operation conditions are investigated in order to obtain information for improving the performance of the SRRC booster synchrotron.
