The Mirror and Cusp Plasma Machine was built at Missouri by the Plasma Program sponsored by the Department of Defense of the United States of America. The machine was designed and custom built by the scientists involved in the plasma research program of University of Missouri-Columbia (UM-C).They ran experiments on it for about ten years and finally donated the equipment to the former Scientific Research & Development Department, now Plasma Engineering Laboratory, of the Polytechnic University of Puerto Rico (PUPR). The equipment was shipped to Puerto Rico and reassembled once again, section by section, with new and updated parts by PUPR engineering students and professors under the leadership and of professor Edbertho Leal-Quirós, Ph.D. Dr. Leal coordinated the whole effort behind the project for the establishment of the Plasma Engineering Laboratory on an advanced modern facility. The PUPR Plasma Engineering Laboratory is the first laboratory of its kind in Puerto Rico and the Caribbean region starting operations in 2004. The Laboratory is under the direction of Dr. Angel E. González-Lizardo, Ph.D. since January 2008.

This machine creates plasma using magnetic field confinement. The machine has two electric magnets that can be used in two different alignments or configurations, spindle Cusp or Mirror mode.  This is one of the advantages of this machine, compared to other designs. The plasma is created by ionizing the gas contained in the machine and confining the ions with a magnetic field. The ionization is achieved by heating the atoms enough so that the electrons on the outer orbit of the atoms are free to displace. The magnetic field creates a flow of electrons that are moving so fast that the ions are not able to recombine with the electrons. This state of the atoms is called plasma.

The Plasma Engineering Laboratory is currently developing research in:

  • Basic physics of Electron Cyclotron Resonance,
  • Ion implantation in a diversity of materials,
  • Basic research in the use of plasma for energy production
  • Plasma Diagnostics using electrostatic probes
  • Magnetic field confinement
