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…
Spatial Control of Photoemitted Electron Beams using a Micro-Lens-Array Transverse-Shaping Technique
A. Halavanau, G. Qiang, G. Ha +4
A common issue encountered in photoemission electron sources used in electron accelerators is the transverse inhomogeneity of the laser distribution resulting from the laser-amplif…
Experiments on bright field and dark field high energy electron imaging with thick target material
Zheng Zhou, Yingchao Du, Shuchun Cao +18
Using a high energy electron beam for the imaging of high density matter with both high spatial-temporal and areal density resolution under extreme states of temperature and pressu…
Effects of Laser Pulse Heating of Copper Photocathodes on High-brightness Electron Beam Production at Blowout Regime
Lianmin Zheng, Yingchao Du, Chuanxiang Tang +1
Producing high-brightness and high-charge (>100 pC) electron bunches at blowout regime requires ultrashort laser pulses with high fluence. The effects of laser pulse heating of the…
Microlens Array Laser Transverse Shaping Technique for Photoemission Electron Source
A. Halavanau, G. Ha, G. Qiang +7
A common issue encountered in photoemission electron sources used in electron accelerators is distortion of the laser spot due to non ideal conditions at all stages of the amplific…
