Online data processing system for multi-pulse and high current beam

The beam online data processing system is an important part of control and diagnoses system on the multi-pulse and high current LIA. The hardware includes many measurement instruments and computers which construct the industrial ethernet network. Many software models are accomplished on LabVIEW which include the measurement network configuration, data collection, computing intensity and position of beam, calibration parameter input display and storage, etc. The method of the resistance ring is applied for beam measurement to the multi-pulse LIA, and the waves of beam intensity and position are achieved according to the oscillograph voltage wave and calibration parameters, and statistical beam parameters are computed based on waves. Two ways for data storage are applied cooperatively. The system runs steadily and reliably on multi-pulse and high current LIA by this time and which gives valid and reliable information for experiment.
