Design Blueprint: A Laser Wakefield Accelerator Stage Sized by Dephasing Length and Plasma Wavelength

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24155273): This paper presents a computed design for a single laser wakefield acceleration stage driven by a 30 fs, 800 nm pulse in a centimetre-scale gas target. The sizing follows from applying the relevant intensity, thermal, nonlinear and geometric bounds at a single stated operating point, with every number produced by a deposited computation. The headline result is a plasma wavelength of 33 micrometres, a dephasing length of 5.4 cm, an accelerating gradient scale of 96 GV/m, and an estimated energy gain of 5.2 GeV over one stage, with the critical-to-plasma density ratio at 1719. The binding constr Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
