Retarding field energy analyzer
WebOct 28, 2009 · Retarding field energy analyzers (RFEA's) have been used to measure IEDs at grounded 1-13 and driven electrodes 14-20 in rf discharges in recent decades. The RFEA has been employed mostly at grounded surfaces as this simplifies the … WebWhile analyzers with higher resolution have flown, generally this comes at the expense of sensitivity and temporal resolution. We present a new technique for measuring plasmas with extremely high energy resolution through the combination of a top-hat Electrostatic Analyzer (ESA) followed by an internally mounted Retarding Potential Analyzer (RPA).
