  A new proton therapy facility is being construted at CIAE. As a part of whole control system, the scanning control system is designed to scan the beam for the access of required tumor therapy field. The origin data plan comes from treatment control system. Two set of dipole magnet is driven for changing the beam path. Meanwhile, interfaces between scanning system and other systems is built for beam control and safe considering. In order to acquire high precise feedback control, the beam position and dose monitor ionization chambers will be constructed in the nozzle. Once accident occurs, the scanning system should be able to response instantly to cut off beam and inform safe interlock system simultaneously. The response time of scanning system is at tens of microsecond level, so the scanning controller, feedback controller and the monitor electronics is built in fast mode. Detailed description will be presented in this paper.
