Terahertz-Driven Nano-tip Field-Emission Electron Gun and Cascaded Acceleration
Wentao Yu, Nongchao Tan, Kai Peng +10
This paper reports two versions of terahertz (THz)-driven nanotip field-emission electron guns: single-layer reflective guns (SLRGs) and double-layer reflective guns (DLRGs). Both…
Observation and Interpretation of Field Emission Saturation Induced by an Ultra-fast Intense Terahertz Field
Wentao Yu, Nongchao Tan, Kai Peng +10
Field emission under ultra-fast intense terahertz fields provides a promising approach for generating electron bunches with ultrashort pulse duration and high charge densities. It…
Advanced RF Structures for Wakefield Acceleration and High-Gradient Research
Xueying Lu, Jiahang Shao, John Power +28
Structure wakefield acceleration (SWFA) is one of the most promising AAC schemes in several recent strategic reports, including DOE's 2016 AAC Roadmap, report on the Advanced and N…
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…
Overestimation of thermal emittance in solenoid scans due to coupled transverse motion
Lianmin Zheng, Jiahang Shao, Yingchao Du +9
The solenoid scan is a widely used method for the in-situ measurement of the thermal emittance in a photocathode gun. The popularity of this method is due to its simplicity and con…
