212 Compact Plasma and Focused Ion Beams
analyzer by recording the peak power corresponding to 2.45 GHz, which is
averaged over 100 shots.
All probes are vacuum-sealed inside a 5.5-mm stainless-steel (SS-304 L)
pipe and inserted via Wilson’s seals. The dimensions of the probes are cho-
sen such that they cause minimal disturbance to the plasma during mea-
surement. The radial measurements are carried out from the top (0°) and
left (270°; see Figure 13.2b) at the center of the MC (z = 15 cm from the MC
entrance). However, it is observed that the measurements from the top direc-
tion cause disturbance in the reected power and the data. This may be ...
