  In the IFMIF EVEDA project*, normal conducting Radio Frequency Quadrupole (RFQ) is used to bunch and accelerate a 130 mA steady beam to 5 MeV. RFQ cavity is divided into 18 modules. The final 3 modules are under test at high power to validate the most critical RF components of RFQ cavity and, on the other hand, to test performances of the main ancillaries that will be used for IFMIF EVEDA project (vacuum system, tuning system and control system). In order to perform RFQ power tests at Legnaro National Laboratories (LNL)**, the RFQ Local Control System (LCS) was extended in order to include also the functionalities and services that, in the final installation, will be in charge of different control systems (e.g. Central Control System, RF system, etc.). The Experimental Physics and Industrial Control System (EPICS) environment*** provides the framework for any equipment and service connected to it. Industrial controls and automation (e.g. Vacuum, Cooling, MPS, PPS and tuning system) are in charge of SIEMENS PLCs and SIEMENS Modular Safety System (MSS)****. This paper reports the configuration and usage of these industrial controls during the RFQ power tests at LNL.

  Legnaro National Laboratories* is involved in IFMIF EVEDA Project** in order to realize the Radio Frequency Quadrupole (RFQ) required to bunch and accelerate a 130 mA steady beam to 5 MeV. Because of the high performances required by this part of the apparatus, one of the most critical task is the RF signals acquisition and the mathematics needed to provide correct parameters for realizing closed loop controls coordinated with other sub-systems composing the RFQ ancillary equipments, the interlocks required by the Machine-Protection System (MPS) and the data for post-analysis. The RF acquisition has been implemented with VME based hardware equipped with VxWorks OS and EPICS framework***,**** while the numerical elaboration has been entrusted to a EPICS softIOC runned on a KVM***** virtual machine. A very important aspect was line calibration; for this purpose a dedicated EPICS tool was developed to standardize and automate the job.
