EPPDyL has a strong history of plasma diagnostics through both direct and indirect methods. The lab has the following capabilities:

Probes

• Langmuir probes (single, double, triple)
• Emissive probes
• Faraday cups
• Mach probes
• B-dot probes
• Retarding Probe Analyzer (RPA)
• Rogowski coils

Probes are usually built by hand for a given experiment

Light and Spectroscopy

• Visible-spectrum spectrometer (400-800 nm)
• SPEX 1702/1704 spectrometer (0-15000 Angstroms)
• Laser-Induced Fluorescence for Argon gas
• Princeton Instruments CCD Camera
• Leeds and Northrup 8620-series Optical Pyrometer
• Multispec MSTI-04V Thermo Imager
• CO2 Spectrum Analyzer 16-A

Radio-frequency

• HP 8757A Vector Network Analyzer
• HP 8553B Spectrum Analyzer
• HP 438A Power Meter
• MFJ HF/VHF Antenna Analyzer
• X-band microwave reflectometry
• Mini-circuits power meters
• Pearson coils

Additional diagnostics

• Lakeshore 425 Gaussmeter
• Residual gas analyzer (QMS200 Prisma, MKS Vac-Check, UTI 100C)
• Various oscilloscopes (up to 1M-points resolution)
