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

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. (C) 2015 Elsevier B.V. All rights reserved.
