Intelligence Summary: Collisional Merging Formation

Node Identity: Collisional Merging Formation is a concept categorized under "Concept" in the china intelligence graph. The FRC formation method used by HFRC, TAE C-2W, and Nihon FAT-CM — two compact toroids are formed and then merged collisionally to create a larger, hotter FRC. This is the dominant international method for sustained FRC operation and is directly applicable to orb weapon plasma generation.
