Structure test results from SLAC (NLCTA) show breakdown and damage at gradients well below expectations from single cavity tests. The papers and presentations listed here illustrate some recent work on the topic. SLAC meeting notes are found here.

Overview - Basic understanding of the role of particulate contaminants (Hasan Padamsee, PAC97)
