Effect of differential cross-section and nsmoothing on Full Problem
The figures below shows Ez(t) and Electron Number(t) for various
cross-section sets and
"nsmoothing" (nsm) factor. Here, "nsmoothing" (nsm) is the number of passes
through
John Verboncoeur's multipass digital filter.
In each case, NR=1.15e17, I= 200 mA, R=1.8 cm, height = 20 cm, and gas T = 300 K.
The Table below shows the output:
