01 Executive_Summary

Dr. Samuel Cohen is a plasma physicist at the Princeton Plasma Physics Laboratory (PPPL) who developed the Princeton Field-Reversed Configuration (PFRC). Cohen's PFRC enables the Direct Fusion Drive (DFD) propulsion concept, connecting LANL's FRC physics to interplanetary propulsion.

02 Definition

03 Deep_Dive_Intelligence

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.
