Building a Start-to-End Model of the CESR Injector Linac
Ryland Goldman, Adam Bartnik, Jared Maxson
The CESR injector linac supplies positrons to the Cornell Electron Storage Ring in six stages: a thermionic cathode, a 150 kV DC gun, a prebuncher, four electron linac sections, a…

Moderator Simulation for the Compact Positron Source at NLCTA
Ryland Goldman, Sophie Crisp, Spencer Gessner
Positron moderation is a key part of the production of slow positrons. This paper examines G4beamline simulations of various moderator designs and the addition of a radiofrequency…

Start-To-End Simulations of a Compact, Linac-Based Positron Source
Sophie Crisp, Ryland Goldman, Arif Ismail +1
Slow positrons are increasingly important to the study of material surfaces. For these kinds of studies, the positrons must have low emittance and relatively high brightness. Unfor…
