Experimental generation of extreme electron beams for advanced accelerator applications
Claudio Emma, Nathan Majernik, Kelly Swanson +13
In this Letter we report on the experimental generation of high energy (10 GeV), ultra-short (fs-duration), ultra-high current (0.1 MA), petawatt peak power electron beams in a par…
A rotor-based multileaf collimator for beam shaping
N. Majernik, G. Andonian, A. Parrack +4
We introduce a new style of multileaf collimator which employs rotors with angularly dependent radius to control the masking aperture: a rotor-based multileaf collimator (RMLC). Us…
Compensating slice emittance growth in high brightness photoinjectors using sacrificial charge
W. H. Li, A. C. Bartnik, A. Fukasawa +5
Achieving maximum electron beam brightness in photoinjectors requires detailed control of the 3D bunch shape and precise tuning of the beam focusing. Even in state-of-the-art desig…
