Microtechnology and Plasma Physics


RSI Princeton Operations specializes in development of new products in microtechnology and plasma physics.Nanopropulsion

Microtechnologies developed at RSI Princeton Ops include the MASS noise-cancelling microspeaker array, the EMP fiber-optic pressure sensor for hypersonic flight, microscale magnetic structures for actuators and charged particle optics, the MIRROR micro-retroreflector array for marking and communications, electron beam windows, and the M2-EMS compact energy-mass spectrograph for charged particle detection in orbit as well as gas sensing on the ground.


Plasma technologies at RSI Princeton Ops include the MET microwave electric thruster for spacecraft, a system for microwave augmentation of supersonic combustors, a microwave plasma aerodynamic control system, the MIRAGE  ionosphere modification system, the CMTX magnetized target fusion plasma source, and the Rotational-Vibrational Spectral Analysis System for plasma monitoring. 


Clients have included the Air Force, NASA, NIST, Lawrence Livermore National Laboratories, the Naval Research Laboratory, and Princeton University. The Princeton Operations have involved a variety of collaborators, including the Aerospace Corporation, Princeton University, Stanford University, and the Ohio State University.

The facility includes 350 square feet of laboratory space with microfabrication clean rooms, an optics lab, a main lab with vacuum chambers for electric propulsion testing and plasma physics, and stations for electronics and mechanical fabrication.  Researchers at the Princeton Operations have held guest staff positions at Princeton University's Mechanical and Aerospace Engineering Department. Princeton's facilities have been used for various projects, including work at Princeton's Institute for the Science and Technology of Materials (PRISM).
