title: [Motion control system in BJ14 medical electron accelerator].
abstract: A dual computer based control mode was used in 14 Mev medical electron accelerator. The special non-linear velocity transformation method makes the positioning operation very fast and convenient. The independent driving mode of four blades are suitable to clinical uses. A multi-interlock function provides a safe environment for user's operation.
