Multipactor Externally driven AWA structures tests at NRL

Multipactor. Power loss vs gradient Electron cloud at different times Multipactor power loss decreases at HG

Simplified representation Ez = 10 MV/m We emit particles at different phases and monitor their incidence energy and corresponding yield

High gradient case Ez = 150 MV/m We are developing a Monte-Carlo simulation based on this idea similar to L. Wu, L.K. Ang Physics of Plasmas 14, 013105 (2007)

Progress on grooved structure development for multipactor studies Grooved structure example: Changing the surface profile by periodically grooving has been found to obviously increase the transmitted power in S-band HPM window breakdown experiment C. Chang et al. J. Appl. Phys. 105, 123305 (2009)

Grooved structure design Ez = 6 MV/m * CST Limited by machining capabilities

Quartz grooved tubes for MP studies Longitudinal Transverse we are set to test ~ 10 different configurations: groove type groove dimension structure length TiN coating Matching sections are designed and being manufactured

summary Multipactor simulation approach is being developed for high gradient regimes (100+ MV/m). It suggests a reduction in MP power loss. We designed and manufactured several grooved structures and they are being prepared for the high power tests
