摘要
The North Carolina atmospheric plasma system (NCAPS) was interfaced with electric diagnostics and computer-based instrument control hardware and software to display plasma parameters in real-time. The monitoring system is also interfaced with gas flow controllers and a Teflon-coated thermocouple for continuous monitoring of the gas flow and the ambient temperature inside the plasma test cell. A simplified plasma model was developed and built in the interface system to solve for the plasma electron number density and display the results during device operation. Polyethylene terephthalate ( PET) films were treated in the device using various gas combinations. The ambient gas temperature inside the test cell increases from 83 to close to 95 degrees F (28.33-35 degrees C) for most gases within 30 s, and further increases to about 105 (40.6 degrees C) after 300 s of operation, indicating a nonthermal
