A tripe-probe method is used to diagnose the average electron energy in a radio frequency (rf) plasma, taking account of effects of non-Maxwellian electron energy distribution function (EEDF) and rf voltage in the probe sheath, i.e. the so-called rf disturbance on diagnostics simultaneously....
Even though, there is a large amount of hardware that can run more samples per day, with the aid of automated sample preparation and ballistic gradients, there may not be any significant change in productivity. This happens because the vital process of data analysis and review is still dependen...
In TLP configuration, two probes are differentially biased to acquire ion-saturation current whereas third probe is kept floating into plasma to measure floating potential. Thus TLP technique enables to measure electron temperature T e , electron number density n e , floating potential V f , and ...
CONSTITUTION:A specimen gas is flowed into a chamber 1, mu-wave power is introduced from an inlet 4, and the chamber 1 is filled with plasma 2. Approaching probes P1-P3 are inserted, and output is switched with a relay switch 5. The probe P2 is measured with an electronic temperature ...
