Cf. Wu et al., Production of uniform plasma with surface electromagnetic wave launched bya waveguide-surfatron, REV SCI INS, 70(2), 1999, pp. 1522-1524
A uniform plasma of large volume is produced by using a new waveguide-surfa
tron. The plasma is uniform within +/-5% in a diameter over 160 mm in the d
iffusion area. The plasma density is 10(10)-10(11) cm(-3) with electron tem
perature 2-4 eV at a microwave power of 500-900 W and a pressure of 10-50 P
