Control and data acquisition for dual HIBP diagnostics in the TJ-II stellarator

Abstract A new set of Heavy Ion Beam Probe diagnostic (HIBP-2) was recently installed in the TJ-II stellarator. HIBP-2 is being operated simultaneously with the previously existing HIBP-1 to provide the coherence data analysis aiming for the 3D studies of the Long-Range Correlations and Alfvenic Eigenmodes. A new Control and Data Acquisition System (CDAS) of high performance and high reliability has been made to operate HIBP-2. The CDAS of HIBP-1 is being upgraded to a similar configuration. The distributed architecture implementing a client–server model provides flexibility and system scalability. The developed CDAS has shown reliable operation of dual HIBP. This paper describes the CDAS of this dual diagnostics.
