Area of Science:

• Laser-plasma physics
• High-intensity laser systems
• Particle acceleration

Background:

• Generating secondary high-intensity laser-plasma sources is crucial for advanced research.
• Existing systems often lack flexibility and precision for complex experimental setups.

Purpose of the Study:

• Integration of adjustable design features for flexible mounting (horizontal/vertical planes).
• Testing of the system at high-intensity laser facilities (COMET and ALEPH).

Main Results:

• The system successfully generates relativistic MeV particles and X-rays at high intensities (≥1 × 10^18 W cm^-2) and high repetition rates (>1 Hz).
• Demonstrated high target placement accuracy (<4 μm RMS) and mechanical stability.
• Experimental data confirmed the generation and focusing of high-intensity laser-driven protons.

Conclusions:
