Accelerator Control Specialist

Overview
The Cornell Laboratory for AcceleratorBased Sciences and Education (CLASSE) carries out research on the frontier of accelerator physics and engineering. CLASSE supports the operation of the Cornell Electron Storage Ring (CESR) for photon science through the Cornell High Energy Synchrotron Source (CHESS). The CHESS organization provides Xray experimental facilities and welcomes users from around the world.

The CESR accelerator group controls and maintains the particle beam accelerator complex required for the CHESS program. This includes creation of an electron beam converting it to antimatter positrons accelerating those positrons to 6 billion electron volts and storing that beam for production of xrays.

The Accelerator Control Specialist will bring technical expertise in accelerator modeling control systems beam physics and scientific computing to the busy CESR group.
