In cylindrical coordinates E is bounded by the planes z=0, z=rcos θ +rsin θ +5 and the cylinders r=2 and r=3, so E is given by y\( (r,θ ,z)|0≤q θ≤q 2π ,2≤q r≤q 3,0≤q z≤q rcos θ +rsin θ +5\). Thus(split)∫∫∫ _Ex&=∫ _0^(2π )...
The theoretical results for the finite cylinder are compared with experimental data on helium, argon, and nitrogen at pressures between 0.1 and 0.5 Torr using a new plasma source. The plasma is produced by a discharge in a region between two concentric cylinders; the inner one, the anode, is...
