Experimental demonstration of cascaded round-to-flat and flat-to-round beam transformations
Seongyeol Kim, Philippe Piot, Gonxiaohui Chen +5
Magnetized beams beam with significant canonical angular momentum are critical to electron cooling of hadron beams such as contemplated in next-generation hadron and electron-ion c…
Four-Dimensional Phase-Space Reconstruction of Flat and Magnetized Beams Using Neural Networks and Differentiable Simulations
Seongyeol Kim, Juan Pablo Gonzalez-Aguilera, Philippe Piot +9
Beams with cross-plane coupling or extreme asymmetries between the two transverse phase spaces are often encountered in particle accelerators. Flat beams with large transverse-emit…
Beam shaping using an ultra-high vacuum multileaf collimator and emittance exchange beamline
N. Majernik, G. Andonian, W. Lynn +9
We report the development of a multileaf collimator (MLC) for charged particle beams, based on independently actuated tungsten strips which can selectively scatter unwanted particl…
Demonstration of sub-GV/m Accelerating Field in a Photoemission Electron Gun Powered by Nanosecond -Band Radiofrequency Pulses
W. H. Tan, S. Antipov, D. S. Doran +11
Radiofrequency (RF) electron guns operating at high accelerating gradients offer a pathway to producing bright electron bunches. Such beams are expected to revolutionize many areas…
Direct Measurement of Eigenemittances Transfer to Projected Emittances via Phase-Space Decoupling for an Electron Beam
Tianzhe Xu, Scott Doran, Wanming Liu +4
Phase-space partitioning offers an attractive path for the precise tailoring of complex dynamical systems. In Beam Physics, the proposed approach involves (i) producing beams with…
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…
