摘要：
We report on recent progress in a program to develop an RF-driven Dielectric-Loaded Accelerating (DLA) structure. capable of supporting high gradient acceleration. Previous high power tests revealed that the earlier DLA structures suffered from multipactor and arcing at the dielectric joint. A few new DLA structures have been designed to alleviate this limitation including the coaxial coupler based DLA structure and the clamped DLA structure. These structures were recently fabricated and high power tested at the NRL X-band Magnicon facility, Results show the multipactor can be reduced by the TiN coating on the dielectric surface. Gradient of 15MV/m has also been tested without dielectric breakdown in the test of the clamped DLA structure. Detailed results are reported, and future plans discussed.
