X-band accelerator structures meeting the Next Linear Collider(NLC) design requirements have been found to suffer damage due to Radio Frequency (RF) breakdown when processed to high gradients. Improved understanding of these breakdown events is desirable for the development of structure designs, fabrication procedures, and processing techniques that minimize structure damage. RF reflected wave analysis and acoustic sensor pickup have provided breakdowns localization in RF structures. Particles contaminant, after the clean autopsy of 3 RF-processed travelling wave structures, have been catalogued and analyzed. Their influence on RF breakdown will be discussed.
