LDRD Compact Positron Source Research AssociateJob ID6139LocationSLAC - Menlo Park, CAFull-TimeTemporarySLAC Job PostingsPosition Overview:SLAC National Accelerator Laboratory is seeking a Research Associate with a proven track record in Positron Trap Science and Technology and/or Low-Energy Beam Physics.In this position, you will be supporting a research effort managed by the Accelerator Directorate and the Laboratory Directed Research and Development (LDRD) program. You will contribute to the design and construction of a positron trap to deliver low emittance positron beams for Accelerator R&D and Materials Science applications. The design concept is detailed in a recent publication (https://journals.aps.org/prab/abstract/10.1103/PhysRevAccelBeams.26.123402) .As part of this project, you will adapt designs of positron traps for pulsed linac sources using the SLAC XTA Beamline. You will work with the high-power electronics group on design and optimization of pulse compression and acceleration systems to reduce the length of the positron bunch after it exits the trap. This work entails modeling of beam transport lines including space charge effects.Please contact Spencer Gessner sgess@slac.stanford.edu if you have questions about the position.Your specific duties include:
Design of positron traps for efficient capture from a pulsed linac source.
Design of positron extraction, compression and acceleration systems.
Modeling of the compact positron source with particle tracking codes.
Construction of the source at the XTA beamline at SLAC's NLCTA facility.
