摘要
High Intensity heavy-ion Accelerator Facility(HIAF)is a heavy ion scientific research facility with an internationally leading level and a wide range of uses.It adopts accelerator cascade to achieve high power and high current intensity.To achieve coordination between devices,the operation of cascade requires high-precision timing scheduling.High-precision timing is the key to precise control of the all equipment,which determines the accuracy and precision of the operation between the equipment.
