Ground-based Plasma Diagnostics and Beam Probes

EPL plasma diagnostics are delivered as ready-to-operate instruments equipped with an in-vacuum wiring harness. Each instrument comes with an instruction manual that explains how to operate the probe, and how to analyze the acquired data to obtain plasma properties.

Measurements that can be made include, but are not limited to, ion and electron flux, ion and electron energy and temperature, plasma potential, plasma density, and ion and electron energy distributions.  Applications for these diagnostics include characterization of plasmas intended to simulate the Earth orbit environment, documentation of plasma and ion beam fields in vacuum facilities, or monitoring of plasma processes.

Ground-based Plasma Diagnostic Data Acquisition System

EPL's custom plasma diagnostic data acquisition systems meet specific customer requirements.  These systems use state-of-the-art data acquisition and control units (analog and digital), precision high voltage biasing control power sources and  advanced software development tools.  Common hardware protocols between the personal computer and the diagnostic system include GPIB and Ethernet.

Custom software user interfaces provide real-time graphical and numeric display of measured and calculated plasma diagnostic parameters.  Data can be captured and saved to disk or printed for review or post-processing. 

Space-based Plasma Diagnostics
 


General Plasma Probe (Flight)GPP-F

Type: Planar with guard ring
Bias capability: Full Langmuir voltage sweep ( 500V)
Status: Flight proven


 

Flight Qualified, Flight Proven Plasma Diagnostics

EPL's space plasma probes measure ion and  electron flux, ion energy, electron temperature, plasma density, and space potential.  These robust diagnostics readily integrate onto spacecraft structures.  They require no standby power and are designed to accept nearly a full hemispherical view of the ambient plasma surrounding the spacecraft.
