Primer of Strong-Field Quantum Electrodynamics for Experimentalists (2511.10315v1)

Abstract: This document serves as a conceptual and practical introduction to Strong-Field Quantum Electrodynamics (SFQED), written from the standpoint of experimental physicists. It was developed in the context of the "Strong-Field QED Workshop 2024" at DESY, aimed at supporting early-career researchers entering the field from the experimental side. Rather than providing a comprehensive theoretical review, the document focuses on the core ideas, terminology, and challenges in SFQED that are most relevant to experimental design and interpretation. Our goal is to offer a first point of contact with the subject, bridging the gap between foundational theory and hands-on experimental work, and complementing more formal literature in the field.
