Under the Broader Approach agreement between Japan and Europe, the Linear IFMIF Prototype Accelerator (LIPAc) aims the validation of the International Fusion Materials Irradiation Facility (IFMIF) accelerator design, to produce a deuteron beam of 125 mA at 9 MeV in continuous wave (CW). While the superconducting linear acceleration stage is being installed, a high-power test bench (HPTB) was set up for the testing and conditioning of four pairs of radio-frequency (RF) couplers for LIPAc RF quadrupole (RFQ). The RFQ RF couplers are a key component to operate LIPAc toward CW.Accordingly, the HPTB control systems (CS) were implemented in parallel to the existing CS of the LIPAc, benefiting from the tools available while avoiding their modification, and additional functionalities and devices were integrated to tackle the specificities of the test bench. This work was continuously performed during the test bench operations, identifying and answering further needs, such as deploying an automated conditioning tool or enabling slow feedback loops for automatic parameter tuning. Furthermore, this test bench became a testing environment for LIPAc CS refurbishments, such as upgrading the CS framework to EPICS v7, switching to CS-Studio Phoebus and its applications for the operator interfaces, or using Debian for the operating systems and ProxMox for the virtual environment. The experience gained will prove valuable for the DEMO-oriented neutron source implementation of IFMIF (IFMIF-DONES). |
