DP2 – Energy-Efficient Solid- State Amplifiers
Overall objective: Solid-State Amplifiers are among the primary energy consumers in particle accelerators. This demonstrator project (DP2) aims to significantly reduce their energy consumption by upgrading their control systems with smart, adaptive technologies and high-efficiency components. DP2a and DP2b will be carried out at ALBA and HZB, respectively, to validate these improvements in real operating conditions.

DP2a
Specific objective:
Improve the energy efficiency of Solid-State Amplifiers (SSA) by upgrading their control systems with intelligent software and energy-efficient hardware.
Demonstrator set-up:
At ALBA, with support from COMMTIA, a high efficiency 1.5 GHz SSA will be retrofitted with a new digital controller. The solution prioritizes software-based upgrades with minimal hardware modifications, enabling scalability to other facilities and/or different operating frequencies. Long-term testing will be conducted to assess reliability and efficiency gains
Expected results:
- Increased energy efficiency at any operating RF level through intelligent control
- Scalable and cost-effective upgrade solution
- Demonstrated long-term performance under real conditions
Research facilities: ALBA
High-tech SMEs: COMMTIA
DP2b
Specific objective:
Enable energy savings in 500 MHz SSA through adaptive control that responds to changing load conditions.
Demonstrator set-up:
At HZB, with support from CRYOELECTRA, a 500 MHz SSA will be retrofitted with an automatic control system that dynamically adjusts the operating point for maximum efficiency. Testing will occur at a dedicated test stand, and potentially within the BESSY II accelerator if scheduling allows.
Expected results:
- Verified energy savings through adaptive, data-driven control
- Operational testing in realistic and high-power environments
- Guidance for broader implementation in similar systems
