Description
The first 100 MeV stage of the MYRRHA superconducting RF linear accelerator is under construction in Mol, Belgium. The machine will produce an instantaneous proton beam current of 4 mA and represents the first step toward the construction of the MYRRHA Accelerator-Driven System (ADS). Such a machine presents several technical challenges for the control of its RF cavities.
First, the required field stability is ≤ 0.1% in amplitude and ≤ 0.1° in phase to avoid excessive beam losses. The high loaded quality factor (𝑄𝐿 = 2.3 × 106) and the need to modulate the beam at 250 Hz require sophisticated field- and detuning-control techniques to keep RF power consumption and stability within specifications.
Finally, since the maximum allowed beam-trip duration is less than 3 s, real-time fault detection and recovery techniques must be implemented in the Low-Level RF (LLRF) controller. To meet these stringent requirements, the MTCA.4 RFSoC-based DAMC-DS5014DR direct-sampling AMC board, currently being developed by DESY, is taken as the performance baseline for the project, for the upcoming tenders.
In this proceeding, the LLRF control strategy foreseen for MYRRHA Phase 1 will be presented. The status of the firmware, software, and analog front-end will also be discussed
