Systematic benchmarking of planar nitrogen-incorporated ultrananocrystalline diamond field emission electron source: rf conditioning and beam spatio-temporal characteristics
Jiahang Shao, Mitchell Schneider, Gongxiaohui Chen +8
Planar nitrogen-incorporated ultrananocrystalline diamond, (N)UNCD, has emerged as a unique field emission source attractive for accelerator applications because of its capability…
Tailoring of an Electron-Bunch Current Distribution via Space-to-Time Mapping of a Transversely-Shaped Photoemission-Laser Pulse
A. Halavanau, Q. Gao, M. Conde +4
Temporally-shaped electron bunches at ultrafast time scales are foreseen to support an array of applications including the development of small-footprint accelerator-based coherent…
Development and high-power testing of an X-band dielectric-loaded power extractor
Jiahang Shao, Chunguang Jing, Eric Wisniewski +5
Dielectric loaded structures are promising candidates for use in the structure wakefield acceleration (SWFA) technique, for both the collinear wakefield and the two-beam accelerati…
Rapid thermal emittance and quantum efficiency mapping of a cesium telluride cathode in an rf photoinjector using multiple laser beamlets
Lianmin Zheng, Jiahang Shao, Eric E. Wisniewski +8
Thermal emittance and quantum efficiency (QE) are key figures of merit of photocathodes, and their uniformity is critical to high-performance photoinjectors. Several QE mapping tec…
Experimental demonstration of the correction of coupled transverse dynamics aberration in an rf photoinjector
Lianmin Zheng, Jiahang Shao, Yingchao Du +9
The production of electron bunches with low transverse emittance approaches the thermal emittance of the photocathode as various aberrations are corrected. Recently, the coupled tr…
Transition radiation in photonic topological crystals: quasi-resonant excitation of robust edge states by a moving charge
Yang Yu, Kueifu Lai, Jiahang Shao +7
We demonstrate, theoretically and experimentally, that a traveling electric charge passing from one photonic crystal into another generates edge waves -- electromagnetic modes with…
