Summary
PPPL physicist who developed PFRC. Enables DFD propulsion. FRC lineage from LANL.
Deep Dive Analysis
Overview
Samuel Cohen is a research physicist at PPPL who developed the Princeton Field-Reversed Configuration (PFRC). The PFRC uses rotating magnetic fields (RMF) to heat and sustain FRC plasmas.
DFD Connection
Cohen's PFRC enables the Direct Fusion Drive (DFD) propulsion concept. Princeton Satellite Systems has developed the DFD concept with NASA funding, using the PFRC as the fusion engine for interplanetary propulsion.
FRC Lineage
Cohen's PFRC work descends from LANL's foundational FRX research. The FRC physics established at LANL in the 1970s-1980s propagated to multiple institutions, with Cohen's PFRC representing the rotating magnetic field approach to FRC heating.
