Abstract : We have performed in situ measurements in two low frequency CFAs to study several basic physics issues which may lead to CFA noise reduction. Our measurements include the local radio-frequency (RF) fields, electron density profiles, electron energy distributions and noise spectrums in both the linear CFA and the reentrant CFA. Comprehensive electron density measurements of the interaction region as well as parametric comparisons such as gain versus sole voltage, beam current and frequency have been used to benchmark two computer simulation codes, MASK and NESSP.
