Photocathode Quantum Efficiency of Ultra-Thin Cs2Te Layers On Nb Substrates
Zikri Yusof, Adam Denchfield, Mark Warren +4
The quantum efficiencies (QE) of photocathodes consisting of bulk Nb substrates coated with thin films of Cs2Te are reported. Using the standard recipe for Cs2Te deposition develop…
Kelvin Probe Studies of Cesium Telluride Photocathode for AWA Photoinjector
Eric Wisniewski, Daniel Velazquez, Zikri Yusof +3
Cesium telluride is an important photocathode as an electron source for particle accelerators. It has a relatively high quantum efficiency (>1%), is sufficiently robust in a photoi…
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…
