Distributed control by EPICS for the SRILAC beam energy position monitoring system using LabVIEW

Beam commissioning for the newly constructed Superconducting RIKEN Heavy-ion Linac (SRILAC) has been successfully completed. Presently, the SRILAC is in operation for promoting super-heavy element searches and radioactive isotope production for medical use. For the stable operation of the SRILAC, non-destructive and highly sensitive measurement by the beam energy and position monitor (BEPM) system is essentially important. Even if the beam intensity is very weak, we can measure the beam position and energy accurately. These measurements and controls are programmed with LabVIEW. On the other hand, by sharing these measured values such as beam positions and beam energies with a large-scale EPICS control system, it became easy to obtain the correlation of each relevant machine parameters in time series.
