Phani Deep Meruga Presents Research at The LLRF Workshop 2025

The biennial Low Level Radio Frequency Workshop (LLRF Workshop 2025), which convenes scientists and engineers worldwide to focus on precision radio frequency systems for particle accelerators took place from the 12-16 October 2025 at the Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Virginia, USA. 

EuPRAXIA DN Fellow Phani Deep Meruga attended the workshop and took the opportunity to present a talk entitled “Development and Testing of a Low-Noise X-Band LLRF Prototype System”. 

The talk highlighted recent progress within the EuPRAXIA-DN project towards achieving ultra-stable RF control in the X-band frequency regime (~12 GHz) for compact accelerator applications. It also detailed the development of a low-noise X-Band LLRF prototype, combining precision analogue front-end design with custom digital back-end electronics, including an in-house 8-channel 250 MS/s ADC module and FPGA-based signal generation and processing. Phani outlined how experimental results have demonstrated pulse-to-pulse amplitude and phase stability within EuPRAXIA’s stringent specifications, with measured phase jitter below 2 fs on the 12 GHz drive signal.

The presentation was well received, drawing strong engagement from experts interested in high-frequency RF control and system integration. The prototype will undergo further evaluation at the TEX facility at INFN-LNF (Frascati, Italy) later in 2025, marking a key step towards its industrialization and deployment in future X-band linear accelerators.
