    • Automation of Plasma Diagnostics at Polytechnic University of Puerto Rico 

      Sánchez, Samuel; Colmenares, Franklyn; González Lizardo, Ángel E.; Leal Quirós, Edbertho (Polytechnic University of Puerto Rico, 2008)
      This work presents an ongoing effort to develop an automatic measurement system for plasma diagnostics at the Plasma Engineering Laboratory of Polytechnic University of Puerto Rico, along with an example of its operation. ...

    • Basic Plasma Diagnostics: Probes and Analyzers 

      Leal Quirós, Edbertho; González Lizardo, Ángel E. (Polytechnic University of Puerto Rico, 2008)
      What is plasma? Plasma is the fourth state of matter. Plasma are conductive assemblies of charged particles, neutrals and fields that exhibit collective effects. Plasma is profoundly influenced by the electrical interaction ...

    • Design of an Automation and Control System for PUPR-MC Plasma Machine 

      Molina, Omar; Morales, E.; González Lizardo, Ángel E.; Leal Quirós, Edbertho (Polytechnic University of Puerto Rico, 2008)
      The automation of Polytechnic University of Puerto Rico Mirror-Cusp (PUPR-MC) plasma machine is part of the work performed by the Plasma Engineering Laboratory in the experiments of the NASA Solar Probe Mission Thermal ...

    • Experimental Design of a High Vacuum System for PUPR-MC Plasma Machine 

      Rivera Varona, Ramón; Colmenares, Franklyn; Leal, David; Lleonart, Giovanni (Polytechnic University of Puerto Rico, 2008)
      In vacuum technology it is customary to divide a large pressure region (as of today, covering 16 orders of magnitude) into single, smaller regions. These divisions are somewhat arbitrary. Thus, the chemists frequently refer ...

    • High Density Plasma Nitriding on Stainless Steel Alloys at PUPR-MC Plasma Machine 

      Rivera, Ramón; Colmenares, Franklyn; Lleonart Dávila, Giovanni; Leal, David; Gaudier, Jorge; González Lizardo, Ángel E.; Leal Quirós, Edbertho; Burgos Saldaña, Gilmer (Polytechnic University of Puerto Rico, 2008)
      A novel method of nitriding at high current levels at Polytechnic University of Puerto Rico Mirror Cusp plasma machine (PUPR-MC) has been performed. Nitrogen ions implantation or plasma nitriding increases the hardness at ...

    • Mass Spectrometric Study of Various Coated Targets Utilizing PUPR-MC Plasma Machine for NASA Solar Probe Space Mission 

      Lleonart Dávila, Giovanni; Leal Quirós, Edbertho; González Lizardo, Ángel E.; Gaudier, Jorge; Rivera, Ramón (Polytechnic University of Puerto Rico, 2008)
      The NASA Solar Probe Space Mission will be a historic operation, flying for the first time into one of the last unexplored regions of the solar system, the Sun's atmosphere or corona; hopefully revolutionizing our knowlege ...

    • Plasma Gas Identification Using the Single Langmuir Probe 

      Sánchez, Samuel; Gaudier, Jorge R.; Rivera, Ramón; Colmenares, Franklin; Lleonart, Giovanni; Carrera, Miguel A.; Molina, Omar (Polytechnic University of Puerto Rico, 2008)
      A novel method to identify mass composition of plasmas was discovered at Polytechnic University of Puerto Rico Mirror Cusp (PUPR-MC) plasma machine using a Single Langmuir probe characteristic. This is a comparative method ...

    • Time Confinement Simulation of a Charged Particle in a Mirror Magnetic Field 

      Ávila O’Neill, Sara R. (Polytechnic University of Puerto Rico, 2016)
      Plasma is a state of matter formed of electrically charged particles. Those particles are greatly influenced by electromagnetic interactions, which have been abundantly studied since the 19 century. The Lorentz equation ...
