Design Blueprint: An Electrostatic Torsion Lens for Charged-Particle Beam Shaping

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24133892): The design presented in this paper is a electrostatic torsion lens intended for shaping ion beams for materials processing and instrument columns. 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. AI-use disclosure: Dave, an AI research system, assisted with the computation and drafting under the author's direction; author of record William Alexander Aldred.
