Damping Ring Optimization in Natural Emittance and IBS Dominated Regimes
Matthew Andorf, Nigel Lockyer, Emilio Nanni +2
Linear electron-positron colliders enable precision measurements of Standard Model observables and beyond. Modern linear colliders need damping rings wherein the emittance of the s…
ESPPU INPUT: C within the "Linear Collider Vision"
Matthew B. Andorf, Mei Bai, Pushpalatha Bhat +34
The Linear Collider Vision calls for a Linear Collider Facility with a physics reach from a Higgs Factory to the TeV-scale with collisions. One of the technologies under…
Measurement of Spin-Polarized Photoemission from Wurtzite and Zinc-Blende Gallium Nitride Photocathodes
S. J. Levenson, M. B. Andorf, B. D. Dickensheets +7
Spin-polarized photoemission from wurtzite and zinc-blende gallium nitride (GaN) photocathodes has been observed and measured for the first time. The p-doped GaN photocathodes were…
Four-Dimensional Emittance Measurements of Ultrafast Electron Diffraction Optics Corrected Up to Sextupole Order
M. Gordon, W. H. Li, M. B. Andorf +7
Ultrafast electron diffraction (UED) is a technique in which short-pulse electron beams can probe the femtosecond-scale evolution of atomic structure in matter driven far from equi…
Operation of Cs-Sb-O activated GaAs in a high voltage DC electron gun at high average current
Jai Kwan Bae, Matthew Andorf, Adam Bartnik +4
Negative Electron Affinity (NEA) activated GaAs photocathodes are the most popular option for generating a high current (> 1 mA) spin-polarized electron beam. Despite its popularit…
A kiloelectron-volt ultrafast electron micro-diffraction apparatus using low emittance semiconductor photocathodes
W. H. Li, C. J. R. Duncan, M. B. Andorf +10
We report the design and performance of a time-resolved electron diffraction apparatus capable of producing intense bunches with simultaneously single digit micron probe size, long…

Optical Stochastic Cooling with an Arc-Bypass in CESR
M. B. Andorf, W. F. Bergan, I. V. Bazarov +4
A proposed experiment to demonstrate Optical Stochastic Cooling (OSC) in the Cornell Electron Storage Ring (CESR) based on an arc-bypass design is presented. This arc-bypass provid…
The Role of Low Intrinsic Emittance in Modern Photoinjector Brightness
Christopher M. Pierce, Matthew B. Andorf, Edmond Lu +8
Reducing the intrinsic emittance of photocathodes is one of the most promising routes to improving the brightness of electron sources. However, when emittance growth occurs during…
