Global Coherency Test — Mainstream Integration Edition: Proposed Protocol for Extended Coherence in Rb-87 Bose-Einstein Condensates

James C. Hanlon III This open-source protocol provides a complete, replicable procedure for investigating extended coherence lengths in a rubidium-87 Bose-Einstein condensate (BEC) using mainstream, off-the-shelf components. The design incorporates silicon carbide (SiC) resonators, chip-scale atomic clock (CSAC) or optical frequency comb (OFC) reference, and AI-edge processing for real-time feedback. Key features:Integration into existing BEC laboratories Estimated incremental cost: ~$4,500 USD Precise 10 Hz reference injection Time-of-flight (TOF) interference imaging for coherence measurement No theoretical claims are made — the document presents only a verifiable experimental procedure. Replicate the build, perform the measurements, and report your results.The protocol includes detailed materials list (BOM), build and operation steps, control arms, metrics, risks/safety guidelines, and references to foundational BEC and related work.
