Title: The Innovative Contributions of Raphael A. Dandl
Introduction
Raphael A. Dandl is a notable inventor based in San Marcos, CA, with a remarkable portfolio of 13 patents. His work primarily focuses on advancements in plasma technology, showcasing his expertise and innovative spirit in the field.
Latest Patents
Dandl's latest patents include the "Slow-wave induction plasma transport" and the "Stand alone plasma vacuum pump." The slow-wave induction plasma transport system utilizes a slow-wave power signal in external radio-frequency (RF) inductors to facilitate the flow of plasmas through ducts. This system creates a magneto-hydrodynamic force that displaces plasma electrons, resulting in a charge separation that drags ions along while slowing down the electrons. This innovative approach allows for a directed stream of energetic ions and neutral gas atoms, maintaining plasma charge neutrality. Additionally, the stand-alone plasma vacuum pump is designed to pump gas from a low-pressure inlet to a high-pressure outlet. It features a housing that encloses multiple pumping regions, permanent magnet assemblies for guiding plasmas, and elements for coupling microwave power to heat electrons and accelerate plasma ions.
