Description
A high electron current is often needed in modern electron accelerators. To achieve this, an energy chirp must be imposed on the bunch so the electrons will compress when they pass through a chicane. This energy chirp is usually imposed by accelerating the beam off-crest from the peak fields of RF cavities, which increases the total length and power requirements of the linear accelerator (linac). A novel concept called the Transverse Deflecting Cavity Based Chirper (TCBC) can be used to impose an energy chirp onto an electron beam, without the need for off-crest acceleration. The TCBC consists of 3 transverse deflecting cavities (TCAVs), which together impose an energy chirp while cancelling out the transverse deflection. An experiment is being developed to demonstrate this concept at the Argonne Wakefield Accelerator (AWA). To run the experiment at AWA, two new TCAVs are under construction, and will arrive at AWA in June 2025. Next the cavities will be cold tested and setup of the experiment will begin. We anticipate running the experiment in late 2025. Here we report on the progress of the experiment and show results from General Particle Tracer* simulations of the beamline.
