Positron Source Simulations for ILC 1 TeV Upgrade
Andriy Ushakov, Gudrid Moortgat-Pick, Sabine Riemann +2
The generation and capture of polarized positrons at a source with a superconducting helical undulator having 4.3 cm period and 500 GeV electron drive beam have been simulated. The…

Transverse Beam Envelope Measurements and the Limitations of the 3-Screen Emittance Method for Space-Charge Dominated Beams
J. G. Power, H. Wang, M. E. Conde +4
In its normal mode of operation the Argonne Wakefield Accelerator Facility uses a high charge (10-100 nC), short pulse (3-5 psec) drive bunch to excite high-gradient accelerating f…

Schottky-Enabled Photoemission in a RF Accelerator Photoinjector - Possible Generation of Ultra-Low Transverse Thermal Emittance Electron Beam
Zikri M. Yusof, Manoel E. Conde, Wei Gai
We present a clear signature of the Schottky effect in a RF photoinjector using photons with energy lower than the Mg cathode work function. This signature is manifested by the shi…
