Under the Broader Approach agreement between Japanand 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 continuouswave (CW). While the superconducting linear accelerationstage is being installed, a high-power test bench (HPTB)was set up for the testing and conditioning of four pairs ofradio-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. Thiswork was continuously performed during the test benchoperations, identifying and answering further needs, suchas deploying an automated conditioning tool or enablingslow feedback loops for automatic parameter tuning. Furthermore, this test bench became a testing environment forLIPAc CS refurbishments, such as upgrading the CSframework to EPICS v7, switching to CS-Studio Phoebusand its applications for the operator interfaces, or usingDebian 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). |
