Description

We report progress on the design of a Phase Diversity Electro-Optic Sampling (DEOS)-based longitudinal profile measurement system. The current design uses THz coherent transition radiation (CTR) to convey the bunch’s longitudinal information. A 1550nm fiber laser available at the Argonne Wakefield Accelerator facility will be used as the probe for electro-optic sampling. Specifically, we discuss pulse synchronization and probe beam transport, the design and optimization of the probe beam stretcher, and the design of the probe beam detection system.
